Linear Technology/Analog Devices LTM4643IV#PBF Ultrathin Quad ?Module� Regulators are quad DC/DC step-down power modules with 3A per output. The outputs can be paralleled in an array for up to a 12A capability. The LTM4643IV#PBF include switching controllers, power FETs, inductors and all support components. The regulators operate over a 4-20V input voltage range or 2.375-20V with an external bias supply. The LTM4643IV#PBF support a 0.6-3.3V output voltage range each set by a single external resistor. The regulators provide a high efficiency design that delivers 3A of continuous output current per channel. Only bulk input and output capacitors are needed.
