APW8805QBI high efficiency 1MHz 3A 5V synchronous step down regulator QFN10

Description

APW8805QBI high efficiency 1MHz 3A 5V synchronous step down regulator QFN10 General Description APW8805A is a 3A synchronous buck converter with integrated 75m Ω high side and 55m Ω low side power MOSFETs. The APW8805A, design with a current-mode control scheme, can convert wide input voltage of 2.6V to 6V to the output voltage adjustable from 0.6V to 6V to provide excellent output voltage regulation. The APW8805A is equipped with force PWM mode operation. The APW8805A is also equipped with Power-on-reset, soft-start, 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 Features: • High Efficiency up to 95% • Adjustable Output Voltage from 0.6V to V VIN • Integrated 75m Ω High Side / 55m Ω Low Side MOSFETs • Low Dropout Operation: 100% Duty Cycle • Mode Selection APW8805A : Force PWM • Stable with Low ESR Ceramic Capacitors • Power-On-Reset Detection on VCC and VIN • Integrated Soft-Start and Soft-Stop • Over-Temperature Protection • Over-Voltage Protection • Under-Voltage Protection • High/ Low Side Current Limit • Power Good Indication • Enable/Shutdown Function • Current-Mode Operation with Internal Compensation • Small TDFN3x3-10 Packages Datasheet
