描述

The DIO61510/A is a high-efficiency synchronous step-down DC-DC regulator. The DIO61510/A can achieve up to 1 A continuous output current from a 2.5 V to 5.5 V input voltage with excellent load and line regulation. The output voltage can be regulated to as low as 0.6 V. Constant on-time(COT) control provides a fast transient response and eases loop stabilization. The DIO61510 includes an automatically entered power save mode to maintain high efficiency down to very light loads for extending the system battery run-time. The DIO61510A runs in Forced PWM maintaining a continuous conduction mode to ensure the least ripple in the output voltage and a quasi-fixed switching frequency. The device features a power good signal. The DIO61510/A is ideal for a wide range of applications, including portable navigation devices, set top boxes and media players.
