3. TECHNICAL BRIEF
3.8.3 TWL6030
The TWL6030 is an integrated Power Management IC for applications powered by a rechargeable battery. The
device provides 7 configurable step-down converters with up to 1.5A capability for Memory, Processor Core, IO,
auxiliary, pre-regulation for LDOs, etc. It contains also 11 LDO regulators which can be supplied either from
battery or from pre-regulated supply. Power up / power down controller is configurable and can support any
Power up / down sequences (EPROM based).
The Real Time clock (RTC) provides 32KHz output buffer, seconds, minutes, hours, day, month, and year
information as well as Alarm wake up. The TWL6030 supports 32KHz clock generation based on crystal oscillator.
The device integrates also a Switch mode charger allowing faster battery charge, higher efficiency & less power
dissipation.
The TWL6030 generates power supplies for OMAP4 and operates together with TWL6040 which includes all
audio and related detection features. For audio IC parameters, see TWL6040 Datasheet. In addition TWL6030 can
be used as PMIC for several other processors, thanks to the programmable startup/shutdown controller and
default supply voltage levels. The TWL6030 is available in an nFBGA package 7.0mm x 7.0mm with 0.4mm ball
pitch.
