AS3606 Power Management Unit

3 Buck DCDCs, 4 LDOs, 1A Linear Charger, General Purpose ADC, Programmable Startup

The AS3606 is an ultra compact System PMU with integrated battery charger and HV back light driver. The programmable power management unit AS3606 includes: 3x 700mA DC-DC step-down converters and 4x low-noise LDOs suitable for RF applications, an LED backlight driver, two current sinks and a Li-Ion battery charger in a small QFN 5x5mm package. The fixed 2 MHz switching frequency minimizes PCB footprint by allowing the use of tiny, low-profile inductors.

Key Features

  • OTP programmable Boot sequence
  • 3DCDC + 3LDOs
  • Li-Ion Charger + Backlight Boost + Sinks

Key Benefits

  • Flexible and fast adaptation to different processors/applications
  • Multiple independent voltage rails
  • Small PCB area for mobile battery powered devices

AS3606 Applications

PDA's, PMP's, GPS Navigation Systems, e-Dictionaries
