Buck Controller (VDDQ) • High Input Voltages Range from 4.5V to 26V Input Power • Provide Adjustable Output Voltage from 0.75V to 3.3V • Integrated MOSFET Drivers and Bootstrap Forward P-CH MOSFET • Low Quiescent Current (200uA) • Excellent Load Transient Responses • PFM Mode for Increased Light Load Efficiency • Constant On-Time Controller Scheme - Switching Frequency Compensation for PWM Mode - Adjustable Switching Frequency from 400kHz to 550kHz in PWM Mode with DC Output Current • S3 and S5 Pins Control The Device in S0, S3 or S4/ S5 State • Power Good Monitoring • 70% Under-Voltage Protection (UVP) • 125% Over-Voltage Protection (OVP) • Adjustable Current-Limit Protection - Using Sense Low-Side MOSFET’s RDS(ON) • TQFN-32 4mmx4mm Thin package • Lead Free Available (RoHS Compliant) +1.5A LDO Section (VTT) • Sourcing and Sinking Current up to 1.5A • Fast Transient Response for Output Voltage • Output Ceramic Capacitors Support at least 10µF MLCC • VTT and VTTREF Track at Half the VDDQSNS by internal divider • +20mV Accuracy for VTT and VTTREF • Independent Over-Current Limit (OCL) • Thermal Shutdown Protection The APW8861 integrates a synchronous buck PWM converter to generate VDDQ, a sourcing and sinking LDO linear regulator to generate VTT.
It offers the lowest total solution cost in system where space is at a premium.
The APW8861 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode.
