A7121A規(guī)格書詳情
DESCRIPTION
The A7121A is a high efficiency synchronous step-down DC-DC converter. Its input voltage range is from 2.7V to 6V and provides an adjustable regulated output voltage from 0.6V to 3.4V while delivering up to 2A of output current.
The current mode architecture of A7121A operation with internal compensation allows the transient response to be optimized over a wide range of loads and output capacitors.
The very low supply current with no load is 60uA and even drops to <1uA in shutdown. The 2.7V to 6.0V input voltage range makes the A7121A ideally designed for single Li-Ion, two to four AA battery-powered applications. It’s 100 duty cycle provides low dropout operation to extend battery life in portable systems.
The PWM pulse skipping mode of A7121A, 1MHz internal switching frequency, allows very small inductors and capacitors and provides very low output ripple voltage for noise sensitive applications.
The A7121A is available in SOT-25 and SOT-26 packages.
