AS3709 : Figure 1: Added Value of using AS3709 The AS3709 is an ultra compact μPMIC containing 5 high-efficiency, constant-frequency synchronous buck converters in addition with two universal IO LDOs are available for lower current power rails. The wide input voltage range (2.7V to 5.5V), automatic power-save mode and minimal external component requirements make the AS3709 perfect for any single Li-Ion battery-powered or fixed 3.3V/5V supply application. Typical supply current with no load is 110μA and decreases to ≤ 7μA in shutdown mode. An internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. The internally fixed switching frequency (2MHz, 3MHz or.
