The CXSD62169 is a 4A, asynchronous, step-down converter with integrated 22mW P-channel MOSFET. The device, with current-mode control scheme, can convert 4.5~26V input voltage to the output voltage adjustable from 0.8 to 100% VIN to provide excellent output voltage regulation. The CXSD62169 regulates the output voltage in automatic PSM/PWM mode operation, depending on the output current, for high efficiency operation over light to full load current. The CXSD62169 is also equipped with power-onreset, soft-start, and whole protections (under-voltage, over-temperature, and current-limit) into a single package. In shutdown mode, the supply current drops below 5mA. This device, available in a TDFN-5x5-16 package, provides a very compact system solution with minimal external components and good thermal conductance.
