APW9213
Active
Dual 2.4MHz, 4A/2A Synchronous Buck Converter
Features
General Description
The APW9213 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. Another feature of this part is its ability to automatically optimize its BW (DyncBandwidth) to allow better dynamic response once it is synchronized to a higher external clock. The converter synchronizes its switching frequency to two times the frequency on the EN/SYNC pin. The APW9213 uses a peak current mode control scheme to regulate the output voltage. The internal switching frequency is set at 2.4MHz. While the EN/SYNC pin supports external clock synchronization. DyncBandwidthTM improves transient response when receiving higher external Synchronization clock. The APW9213 is offered in a VTQFN3x2-18 package allowing small size while having an excellent thermal capability for power dissipation.
