APW9211S
Active
High Efficiency 16V, 2-CH Buck Converter
Features
- N-CH MOSFET (45mΩ) for CH1 Low Side
- N-CH MOSFET (95mΩ) for CH2 High Side
- N-CH MOSFET (55mΩ) for CH2 Low Side
General Description
The APW9211S is a two-channel synchronous mode PWM converter with 4A continuous current capability for one channel and 2A continuous current capability for the other one. Each channel of the APW9211S has independent enable, and it also allows the two regulators to start together by using the same enable signal and the same soft-start capacitor. Although the switching frequency of the APW9211S is fixed at 600kHz. The APW9211S also provides a 180-degree phase shifting technique to minimize switching noise. The output voltage of each channel can be adjusted using an external resistor divider. Other features include UVP, current limit, and OTP. The APW9211S is available in a VTQFN2x2-13 package with small size and excellent thermal capacity.
