UM3433 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...
