Overview
Preliminary Datasheet 1.
3MHz, Dual 1.
0A Synchronous Step-down Converters AP3421/A/B General Description The AP3421/A/B is a fully integrated dual output voltage regulator.
The two converters are current mode and internally compensated.
The converters include integrated control and synchronous rectifier switches.
The outputs are both rated for up to 1A.
Both outputs are adjustable using external resistors.
The step-down converters operate at 1.
3MHz fixed switching frequency under normal load and in a pulse skipping mode for light loads.
The switching clock is shifted 180° for SW2.
The E/S pin provides an enable function and allows the converter to be synchronized to an external clock.
