APW7436
Active
3-CH Buck Converter, 4.5-24V Input Voltage, Tiny Package
Features
- N-CH MOSFET (30 mΩ) for CH1 Low Side
- N-CH MOSFET (50 mΩ) for CH2/3 Low Side
General Description
The APW7436 is a three-channel synchronous mode PWM converter with 2.5A continuous current capability for one channel and 1.5A continuous current capability for the other two channels. Although the switching frequency of the APW7436 is fixed at 600kHz, it can also change the switching frequency via the SYNC pin. The APW7436 also provides a 120-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 OVP, UVP, current limit, and OTP. The APW7436 is available in a TQFN3x3-20A package with small size and excellent thermal capacity.
Features
- Wide Input Voltage from 4.5V to 18V
- 2.5A/1.5A/1.5A Output Current on Channel1/2/3
- Low IQ=160μA (typ.) per channel supply to improve Light Load Efficiency at Sync off
- Typical 0.6V ±1%Internal Reference Voltage
- Sync Pin Allows Synchronization to an External
- Clock from 500kHz to 2MHz
- Optimized Upper and Lower MOSFETs RDS_on for max Efficiency :
- N-CH MOSFET (30 mΩ) for CH1 Low Side
- N-CH MOSFET (50 mΩ) for CH2/3 Low Side
- Built in OVP, UVP, Current Limit and OTP
- Low Cost TQFN3x3-20A package
- Lead Free and Green Devices Available (RoHS Compliant)
