OKLP-X/60-W12A-C www.murata-ps.com 60A Power Block Non-Isolated DC-DC Converter Typical uni unit FEATURES PRODUCT OVERVIEW High efficiency (95% @12Vin, 3.3Vout) The “60A Power Block” is an 115.5W, nonisolated DC-DC converter. This DC-DC module is a structure block for a new open digital power design developed to work with either digital or analog controllers, with an input range of 7-13.2VDC and a regulated output of 0.6-3.63VDC, with load current up to 60A at 0.6V to 1.32V output voltage. The Power Block is a synchronous buck converter. The two phases can be tied together and can current share as a single output, or they can be separated Power Block (60A, 7-13.2Vin, 0.6-3.63Vout, SMT) Input under-voltage lockout Small footprint (1" [25.4] x 0.5" [12.7] x 0.48" [12.2]) No minimum load required Low Output Ripple -40°C to +85°C operating temperature as two different outputs. It has been implemented using a synchronous buck gate driver IC with co-packed control and synchronous MOSFETs and Schottky diode. The output filter consists of 270nH inductance and 10μF capacitance. A Low Drop out Voltage Regulator is used to provide regulated 7V VCC to the gate driver IC. A Voltage Detector is used to shut down the gate driver when VCC drops below limit.
