3A, Point-of-load, Chopper-type Step-down Converter

The LV5781 is a 1-channel chopper-type (low-side Schottky diode) Step-down Switching Regulator It incorporates an 80m, (typical) Power MOSFET to achieve high-efficiency operation for 3A output currents. The output voltage is set internally to 3.3V. By adding two external resistors, it is possible to set the voltage to any desired setting above 0.85V. Inrush current at startup CAN be prevented by the soft start function. Using the ON/OFF pins, the converter CAN be set to standby mode in which the current consumption is 10 or less. Both the load and the IC are protected by means of the overcurrent and thermal protection functions. The converter uses the HSSOP14 miniature package. By Sanyo Semiconductor Corporation
