Overview
UM3429
600mA, 1MHz, Synchronous Step-Up DC-DC Converter UM3429S SOT23-6
General Description
The UM3429 is synchronous rectified, fixed frequency, step-up DC/DC converter series delivering high efficiency in low profile SOT23-6 package.
It features 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 ...
