General Description

This is a 5+2 CH integrated PMIC for DV application.

There are 5 DC/DC converters : one synchronous step-up, one selectable synchronous step-up/step-down, two synchronous step-downs, and one WLED driver in either asynchronous step-up or current source mode, selectable by VOUT6 initial voltage.

In addition, there are 2 LDO regulators : one RTC LDO and one generic LDO.

Key Features

  • All Power MOSFETs Integrated.
  • 5 Channels with Internal Compensation.
  • Flexible Enabling Control  Enabled Independently or in Preset Power On/ Off Sequences.
  • CH2 Synchronous Converter in Step-Up or StepDown Mode Selectable by SEL Pin.
  • Synchronous Step-Down DC/DC Converter  Up to 95% Efficiency  100% (max) Duty Cycle.
  • Synchronous Step-Up DC/DC Converter  Adjustable Output Voltage  Up to 95% Efficiency.
  • Asynchronous Step-Up Converter to Drive WLED, Selectable.
