Datasheet Details

Part number	UM3429
Manufacturer	UniON Semiconductor
File Size	517.45 KB
Description	Synchronous Step-Up DC-DC Converter
Datasheet	UM3429-UnionSemiconductor.pdf

The UM3429 is synchronous rectified, fixed frequency, step-up DC/DC converter series delivering high efficiency in low profile SOT23-6 package.

true output load disconnection and adjustable output. With an internal NMOS switch, PMOS synchronous rectifier and high switching frequency of 1MHz, the UM3429 is capable of supplying 3.3V output at 100mA from a single AA cell input or 250mA from a 2-cell AA input using low profile inductors and ceramic capacitors. Current mode PWM control with internal compensation as well as the synchronous rectifier and 1MHz high frequency lead to the fewest number of external parts needed thereby saving BOM.
