AP3211H

OBSOLETE – PART DISCONTINUED PART OBSOLETE - USE AP3211 and AP5100 Preliminary Datasheet 1.4MHz, 1.5A ASYNCHRONOUS DC-DC BUCK CONVERTER AP3211H General Description The AP3211H 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-by-cycle current limit. A standard series of inductors are available from several different manufacturers optimized for use with the AP3211H. This feature greatly simplifies the design of switch-mode power supplies. The AP3211H is available in SOT-23-6 package. Features Input Voltage Range: 4.5V to 23V Fixed 1.4MHz Frequency High Efficiency: up to 92% Output Current: 1.5A Current Mode Control Built-in Over Current Protection Built-in Thermal Shutdown Function Built-in UVL...
