AX3702 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 about 200uA and drops to <1uA in shutdown. The 2.5V to
    7.5V input voltage range makes AX3702 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. PWM pulse skipping mode operation provides very low
    output ripple voltage for noise sensitive applications. Switching frequency is internally set at
    1.2MHz, allowing the use of small surface mount inductors and capacitors. The internal
    synchronous switch increases efficiency and decreases need of an external Schottky diode.
    Low output voltages are easily supported with the 0.6V feedback reference voltage. AX3702
    is available in small SOT-23-5L, SOT-23-6L, TDFN-10L (3*3), and SOP-8L-EP packages.
