APW9170C
Active
2A, 5V Input, Synchronous Buck Converter
Features
General Description
The APW9170C is a 2A synchronous buck converter that uses constant on time mode control scheme to convert wide input voltage of 2.7V to 5.5V to outputs as low as 0.6V while providing excellent output voltage regulation. The APW9170C is also equipped with Power-on-reset, internal soft start and complete protections (under-voltage, over temperature and current-limit) into low cost TDFN2x2-6A and TSOT23-6A packages. The IC also provides output capacitor discharge when it is disabled via the discharge MOSFET.
Features
- Input Voltage Range: 2.7V to 5.5V
