Power Electronics / Power Management
The AS3607 from austriamicrosystems is a highly integrated power management IC (PMIC) featuring a high level of startup sequence programmability, making it suitable for portable navigation devices, portable media players, e-dictionaries, GPS devices, PDAs and a wide range of battery powered handheld devices using ARM-based processors.
The output voltage and the timing of all regulators of the AS3607 are programmed via software. With the software and demo board, the OTP memory of the device can be programmed easily for fast prototype runs. The slope of the ramp can be set for the step-down converters. The user can program the startup sequence with timing steps of 1 ms or 4 ms, ensuring that all ARM-based processors can easily be covered. In order to control other parts of the system, the general-purpose I/O pins can be programmed to a specific timing.
In its 6 x 6 mm QFN package, the power management unit includes three DC-DC step-down converters and five low-noise LDO regulators suitable for RF applications, an LED backlight driver, two programmable current sinks and a Li-Ion battery charger. The three step-down converters deliver 700 mA each with an efficiency of up to 95%; the fixed 2 MHz switching frequency minimises PCB footprint by allowing the use of tiny inductors.
