3A同步降压变换器CXSD62177自动PFM/PWM模式操作低ESR陶瓷电容器稳定VCC和VIN上电复位检测

CXSD62177 CXSD62177A CXSD62177B is a 3A synchronous buck converter with integrated 75mW high side and 55mW low side power MOSFETs. The CXSD62177 CXSD62177A CXSD62177B, design with a current-mode control scheme, can convert wide input voltage of 2.6V to 6V to the output voltage adjustable from 0.8V to 6V to provide excellent output voltage regulation. The CXSD62177 CXSD62177A CXSD62177B is equipped with an automatic PFM/PWM mode operation. At light load , the IC operates in the PFM mode to reduce the switching losses. At heavy load, the IC works in PWM mode. At PWM mode, the switching frequency is set by the external resistor. The CXSD62177 CXSD62177A CXSD62177B is also equipped with Power-on-reset, softstart, soft-stop, and whole protections (under-voltage, over-voltage, over-temperature and current-limit) into a single package. This device, available TDFN3x3-10, provides a very compact system solution external components and PCB area
