Overview
UM3433
600mA, 600kHz Step-Up DC-DC Converter
UM3433 SOT23-6
General Description
The UM3433 is synchronous rectified, fixed frequency, step-up DC/DC converter series delivering high efficiency in a low profile SOT23-6 package.
It is available both in 3.
3V/3.
0V fixed output and adjustable output.
With an internal NMOS switch and PMOS synchronous rectifier and high switching frequency of 600KHz, the UM3433 is capable of supplying 3.
3V output at 100mA from a single AA cell input using low profile inductors and ceramic capacitors.
Current mode PWM control with internal compensation cuts external parts count thereby saving BOM cost and PCB real estate.
At light loads, UM3433 enters automatically ...
