DA9061
PMIC for applications requiring up to 6 A
General Description
DA9061 is a power management integrated circuit (PMIC) optimized for supplying systems with
single- and dual-core processors, I/O, DDR memory, and peripherals. It targets mobile device,
medical equipment, IVI systems, and FPGA based applications.
DA9061 features three buck converters providing a total current of 6 A. High efficiency is achieved
over a wide load range by using automatic Pulse Frequency Modulation (PFM) mode. All power
switches are integrated, therefore, external Schottky diodes are not required. Furthermore, low-
profile inductors can be used with DA9061. The four LDO regulators with programmable output
voltage provide up to 300 mA.
Dynamic voltage control (DVC) allows dynamic control of DA9061 supply voltages according to the
operating point of the system. It is controlled by writing directly to the registers using the I²C
compatible 2-wire interface or the GPIOs.
DA9061 features a programmable power sequencer that handles start-up and shutdown sequences.
Power mode transitions can be triggered with software control, GPIOs, or with the on-key. Several
types of on-key presses can be detected to trigger different power mode transitions.
An integrated watchdog timer monitors the system.
Five GPIOs are able to perform system functions, including: keypad supervision, application buck,
and timing-controlled external regulators/power switches or other ICs.
DA9061 is also available as an automotive AEC-Q100 Grade 3 version.
