The Power Management Platform is silicon proven, customizable integrated power management subsystem which provides a cost-effective single-chip solution for power management. Typical target applications include portable low-power consumer products or any application, with a need to control diverse power domains.
This customizable platform incorporates programmable DC-DC converters, and multiple LDO’s. The DC-DC converters deliver high efficiency across a wide range of operating conditions and can be optimized to support high load transients seen in typical processor cores.
The Power Management Platform includes a crystal oscillator driver and an internal RC oscillator to generate all clock signals for autonomous system start-up and processor clocking requirements. The start-up behavior and configuration are fully programmable via integrated OTP memory. Hence, the optimized sequencing of power and system clock is provided for multiple domains.
Also incorporated is a low power 12-bit ADC which can be used for numerous analog sampling needs, such as temperature or voltage sensing. Robust POR, bandgap reference and bias circuitry are also included.
For portable devices, battery life can be maximized due to the highly segmented power control provided. These are accessed via a control interface or alternatively via OTP-configurable GPIOs.
This customizable power management platform enables an optimized power control system, which allows for a lower-risk, shorter time-to-market.
