It is based on ETAs ETA3707 buck converter with built-in power MOSFETs, inductorand capacitor.
The integrated structure simplifies the power system design.
The EM3707/EM3707T can provide programmable output voltages from 1.2V to 3.3V, and capable to deliver up to 1A of output current.
The EM3707A/EM3707AT can provide programmable output voltages from 0.7V to 3.1V, and capable to deliver up to 500mA of output current.
The EM3707B/EM3707BT can provide programmable output voltages from 0.5V to 1.9V, and capable to deliver up to 500mA of output current.
The core features of the whole series cover:
- Wide input voltage range: 2.1V-5.5V
