TOREX SEMICONDUCTOR XCL205
the XCL205 series is PWM control, the XCL206 series is automatic PWM/PFM switching control and the XCL207 series can be manually switched between the PWM control mode and the0automatic PWM/PFM switching control mode, allowing fast response, low ripple and high efficiency over the full range of loads (from light load to heavy load). With the built-in UVLO (Under Voltage Lock Out) function, the internal driver transistor is forced OFF when input voltage becomes 1.4V or lower.
