GENERAL DESCRIPTION
Figure 1: Added Value of using AS3709 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. Very low output voltages can be delivered with the internal 0.6V feedback reference voltage. The AS3709 is available in a 32-pin QFN 4x4mm package and in a very compact CSP36 with 0.4mm pitch. For further understanding in regards to the contents of the datasheet, please refer to the Reference Guide located at the end of the document. Key Benefits & FEATURES
The benefits and features of AS3709, μPMIC with 5 DCDC and 2 LDOs are listed below: Benefits FEATURES
Compact design due to small coils for IO and memory voltage generation 5 DCDC step down regulators (2-4MHz) Independent voltage rails for general purpose IO supplies 2 universal IO LDOs Flexible and fast adaptation to different processors/applications OTP programmable Boot and Power-down sequence Power saving control according to the processor‘s needs.
