AP3211 Datasheet | Diodes Incorporated

1.4MHZ,1.5A ASYNCHRONOUS DC-DC BUCK CONVERTER Description The AP3211 is a 1.4MHz fixed frequency, current mode, PWM buck (step-down) DC-DC converter, capable of driving a 1.5A load with high efficiency, excellent line and load regulation. The device integrates N-channel power MOSFET switch with low on-resistance. Current mode control provides fast transient response and cycle-bycycle current limit. A standard series of inductors are available from several different manufacturers optimized for use with the AP3211. This feature greatly simplifies the design of switch-mode power supplies. The AP3211 is available in SOT-23-6 package.
