Analog Devices ADP1864 Datasheet

www.DataSheet4U.com Constant Frequency Current-Mode Step-Down DC/DC Controller in TSOT ADP1864 FEATURES Wide input voltage range: 3.15 V to 14 V Wide output voltage range: 0.8 V to input voltage Pin-to-pin compatible with LTC1772, LTC3801 Up to 94% efficiency 0.8 V ±1.25% reference accuracy over temperature Internal soft start 100% duty cycle for low dropout voltage Current-mode operation for good line and load transient response 7 μA shutdown current 235 μA quiescent supply current Short-circuit and overvoltage protection Small 6-lead TSOT package GENERAL DESCRIPTION The ADP1864 is a compact, inexpensive, constant-frequency current-mode step-down DC-to-DC controller. The ADP1864 drives a P-channel MOSFET that regulates an output voltage as low as 0.8 V with ±2% accuracy, for up to 5 A load currents, from input voltages as high as 14 V. The ADP1864 provides system flexibility by allowing accurate setting of the current limit with an external resistor, while the output voltage is easi.
