TVS ESD Conclusion
• IC’s must be protected because most of them cannot withstand
ESD conditions higher than 2kV.
• ON Semiconductor devices showed the best performance
to suppress ESD pulses generated by the IEC 61000-4-2
ESD standard.
• PCB lay-out is critical to improve ESD protection and reduce the
parasitic effects (V=Ldi/dt).
• Varistors do not offer an effective ESD protection because their
clamping voltage is too high. They cannot be used for protection
in high speed data lines either because of their high capacitance.
• Semtech’s devices are more sensitive to board parasitic effects,
which could be due to higher package’s inductance.

EMI Types and Generation
EMI类型和产生
1.- Conducted EMI is noise fed back from a system onto the AC or DC power line or signal lines. This noise is in the
frequency range of 10KHz to 30MHz. It usually has a common mode component and a differential mode component.
The common mode component appears as a voltage on both line and neutral leads with respect to ground or earth
while the differential mode appears between the line and neutral leads. To suppress conducted EMI, LC networks are
usually used.
传导EMI是从系统反馈到交流或直流电源线或信号线的噪声。这种噪声的频率范围从10KHz 到 30MHz。它通常有一个共模分量
和一个差模分量。共模分量是施加在火线和中线上的对地电压。差模出现在火线和中线之间。为了抑制传导EMI，通常使用LC
网络。
2.- Radiated EMI comes in the form of electromagnetic waves radiating directly from the circuitry and leads of a
system. A common example is the AC power cord of the system which can act as a transmitting antenna for radiated
EMI. Ranging from 30MHz to 1GHz, this type of noise can be effectively suppressed by metal shielding around the
source.
辐射EMI以直接从系统电路和导线辐射出来的电磁波形式出现。常见的实例是系统的交流电源线作为辐射EMI的发射天线。频率
范围从30MHz 到 1GHz，这种噪声可以被源周围的金属屏蔽有效抑制。

NTHD4P02FT1-FETKY™
MOSFET Plus Schottky Rectifier
Description
Ultra-small eight lead package allows the integration of a
MOSFET and Schottky Rectifier into one package.
This is the smallest FETKY™ on the market with a maximum
footprint of 3.10 X 2.00 mm to optimize board space.
 Independent pin out to each device to increase design
flexibility, i.e. use Schottky as blocking diode or in parallel with
body diode.
Applications
 Any handheld application, including
Cellular phones, Digital Cameras, MP3s,
and PDAs that requires DC-DC converters
(buck, buck-boost, and synchronous
rectification).
Charge control in portables
Features
 New smaller ChipFET™ in 8 lead package (1.9 X 3.0 mm)
 P-Channel MOSFET, VDDS= 20V, RDS(on)=130mΩ @ VGS = 4.5V
 SCHOTTKY VR=20V, with Low VF =0.32V @ 1 Amp
Benefits
Product Availability:

 Samples Now
 Production Jan/03

Previously only available in SO-8 package (5 X 6 mm)
Higher efficiency, reduced battery drain.
 Less voltage drop across the diode.

NCP2890 1 watt Audio Amplifier
Description
The NCP2890 is an audio power amplifier capable of delivering 1W of continuous
average power to an 8 W load from a 5V-power supply, and 320 mW to a 4 W load
from a 2.6V power supply. The NCP2890 provides high quality audio while
requiring few external components and minimal power consumption. It features a
low-power consumption shutdown mode, which is achieved by driving the
shutdown pin with logic low. The NCP2890 contains circuitry to prevent from “pop
and click” noise that would otherwise occur during turn-on and turn-off transitions.
For maximum flexibility, the NCP2890 provides an externally controlled gain (with
resistors), as well as an externally controlled turn-on and turn-off times (with the
bypass capacitor).

NCP2809: NOCAP™ 135mW Stereo
Headphone Power Amplifier
Description
Already RTM
The NCP2809 is a cost-effective stereo audio power amplifier capable of delivering 135mW
per channel of continuous average power per channel into 16 W loads.
The NCP2809 audio power amplifier is specifically designed to provide high quality output
power from low supply voltage, requiring very few external components. Since NCP2809
does not require bootstrap capacitors or snubber networks, it is optimally suited for low
power portable systems. NCP2809A has an internal gain of 0dB while specific external gain
can externally be set with NCP2809B .
If the application allows it, the virtual ground provided by the device can be connected to
the middle point of the headset. In such case, the two external heavy coupling capacitors are Applications
useless. Otherwise, you can also use both outputs in single ended mode with external
coupling capacitors.
 Portable stereo
Due to its excellent PSRR, it can be directly connected to the battery, saving the use of a
LDO.

NCP1501
Buck Converter with Synchronous Rectification
and LDO Mode
Description
NCP1501 is a dual mode regulator that operates either as a PWM Buck
Converter or as a Low Drop Out Linear Regulator. If a synchronization signal
is present, the NCP1501 operates as a current mode PWM converter with
synchronous rectification. The synchronization signal allows the user to
control the location of the spurious frequency noise generated by a PWM
converter. Linear mode is active when a synchronization signal is not present.
The NCP1501 configuration allows an efficient high power operation and low
noise during system sleep modes.
Features
Benefits
 Synchronous Rectification in PWM Mode (>300 mA Iout) and 800
mA peak inductor current
 Linear Mode Operation at Low Loads up to 50 mA

 Current Mode PWM with Cycle by Cycle Current Limit
 Designed for use with ceramic capacitors
 Operating Frequency Range of 500 to 1000 kHz

NCP1800
Single-Cell Li+ Battery Charge Controller
Description
The NCP1800 is a constant current, constant voltage
(CCCV) lithium ion battery charge controller. The external
sense resistor sets the full charging current and the
termination current is 10% of the full charge current (0.1
C). The voltage is regulated at +1% during the final
charge stage. There is virtually zero drain on the battery
when the input power is removed.
Features
 4-phase charging algorithm
 Integrated voltage and programmable current
regulation.
 Integrated cell conditioning for deeply discharged
cell.
 Better than 1% voltage regulation.
 Lowest standby current (0.5uA) in the industry.
 Charger status output for LED or host processor
interface.
 Blocking diode not required with PNP transistor.
 Integrated over-voltage protection.
 Micro8TM package.
