3.10.3 TWL5034
The TWL5034 is an integrated power management for mobile devices that use the OMAP’s application
processors (AP), or other similar application processors. The TWL5034 includes three high efficiency step-down
regulators and 17 LDOs to power the application processor, internal Logic, I/O, memory, and system accessories.
An additional the device provides LED driver circuitry to power two LED circuits(LED A,LEDB)
that can illuminate a panel or provide user indicators. The LED A can provide up to 160 mA and the
LED B, 50 mA. Each LED circuit is independently controllable for basic power (on/off) control and
illumination level (using PWM).
