ADP1621 - Current-Mode Step-Up DC/DC Controller

The ADP1621 is a fixed-frequency, pulse-width modulation (PWM), current-mode, step-up converter controller. It drives an external n-channel MOSFET to convert the input voltage to a higher output voltage. The ADP1621 can also be used to drive flyback, SEPIC, and forward converter topologies, either i.

ADP1621 Features

* 92% efficiency (no sense resistor required) ±1.0% initial accuracy IC supply voltage range: 2.9 V to 5.5 V Power-input voltage as low as 1.0 V Capable of high supply input voltage (>5.5 V) with an external NPN or a resistor VIN UVLO and 35 mA shunt regulator External slope compensation with 1 resist
