AP3407KTR-G1

AP3407/A PART OBSOLETE – CONTACT US 1.2A, 1.4MHZ HIGH EFFICIENCY SYNCHRONOUS DC-DC BUCK CONVERTER OBSOLETE – PART DISCONTINUED Description Pin Assignments The AP3407/A is a 1.4MHz fixed frequency, current mode, PWM synchronous buck (step-down) DC-DC converter, capable of driving a 1.2A load with high efficiency, excellent line and load regulation. The device integrates synchronous P-channel and N-channel power MOSFET switches with low on-resistance. It is ideal for powering portable equipment that runs from a single Li-ion battery. (Top View) A standard series of inductors are available from several different manufacturers optimized for use with the AP3407/A. This feature greatly simplifies the design of switch-mode power supplies. EN 1 GND 2 SW 3 FB 4 VIN SOT-23-5 for AP3407 The AP3407/A is available in SOT-23-5.
