The PMU/tongsheng/52.html target=_blank class=infotextkey>PMU/tongsheng/2019/11/25/1172.html target=_blank class=infotextkey>CXSB6612 series is available in an ultra small package USP-12B01 suited for space conscious applications. The PMU/tongsheng/52.html target=_blank class=infotextkey>PMU/tongsheng/2019/11/25/1172.html target=_blank class=infotextkey>CXSB6612 series is a group of synchronous-rectification type DC/DC converters with a built-in 0.42ΩP-channel MOS driver transistor and 0.52ΩN-channel MOS switching transistor, designed to allow the use of ceramic capacitors. The ICs enable a high efficiency, stable power supply with an output current of 600mA to be configured using only a coil and two capacitors connected externally. Operating voltage range is from 2.7V to 6.0V. With the built-in oscillator, either 1.2MHz or 3.0MHz can be selected for suiting to your particular application. As for operation mode, the PMU/tongsheng/52.html target=_blank class=infotextkey>PMU/tongsheng/2019/11/25/1172.html target=_blank class=infotextkey>CXSB6612xA / PMU/tongsheng/52.html target=_blank class=infotextkey>PMU/tongsheng/2019/11/25/1172.html target=_blank class=infotextkey>CXSB6612xB series are PWM control, the PMU/tongsheng/52.html target=_blank class=infotextkey>PMU/tongsheng/2019/11/25/1172.html target=_blank class=infotextkey>CXSB6612xC / PMU/tongsheng/52.html target=_blank class=infotextkey>PMU/tongsheng/2019/11/25/1172.html target=_blank class=infotextkey>CXSB6612xD series are automatic PWM/PFM switching control, allowing fast response, low ripple and high efficiency over the full range of loads (from light load to heavy load). The soft start and current control functions are internally optimized. During stand-by, all circuits are shutdown to reduce current consumption to as low as 1.0μA or less. With the built-in UVLO (Under Voltage Lock Out) function, the internal P-channel driver transistor is forced OFF when input voltage becomes 1.4V or lower.
