TOREX SEMICONDUCTOR XC9216

the XC9216 series is automatic PWM/PFM switching control and the XC9217 series can be manually switched between the PWM control mode and the automatic PWM/PFM switching control mode, allowing fast response, low ripple and high efficiency over the full range of load (from light load to high output current conditions). The soft start and current control functions are internally optimized. With the built-in U.V.L.O.

GENERAL DESCRIPTION

The XC9215/9216/9217 series is a group of synchronous-rectification type DC/DC converters with a built-in 0.6 Ω P-channel driver transistor and 0.7Ω N-channel switching transistor, designed to allow the use of ceramic capacitors. The ICs enable a high efficiency, stable power supply with an output current of 500 mA to be configured using only a coil and two capacitors connected externally. Minimum operating voltage is 2.0 V.
