DESCRIPTION

The A7116 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version. Supply current with no load is 40μA and drops to <1uA in shutdown. The 2.5V to 6.8V input voltage range makes the A7116 ideally suited for single Li-Ion, two to four AA battery-powered applications. 100 duty cycle provides low dropout operation, extending battery life in portable systems. In power saving mode, 40μA quiescent current is very suitable for DSP/MCU in standby operation; and in PWM mode, low output ripple voltage is good enough for noise sensitive applications. The two modes can be automatically switched according to the load current.

Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.6V feedback reference voltage. The A7116 is available in a SOT-25 package.

The A7116 is available in SOT-25 package.
