uP1911R
Key Features
- It consists of three individual sequence circuits to support up to 2 to 4 phase extension application
- This part has 4 PWM outputs for external MOSFET drivers, and 4 ISEN inputs
- With this phase extender, a 2-phase buck PWM controller is able to control a 4-phase synchronous buck regulator
- This device has an internal LDO that regulates 12V input to a 5.2V output as the power supply of control logic
- Designed with 12V CMOS process, the uP1911R provides high switching speed and low power dissipation
- The uP1911R is available in WQFN3x3 - 16L package
