AP3421 Datasheet (BCD Semiconductor) - Dual 1.0A Synchronous Step-down Converters

AP3421, Dual 1.0A Synchronous Step-down Converters

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 resist
