Product Summary
The OMAP4470CBL is an integrated power-management integrated circuit (PMIC). The OMAP4470CBL provides five configurable step-down converters with up to 5.0-A current capability for memory, processor core, I/O, auxiliary, preregulation for LDOs, etc. It also contains nine LDO regulators for external use that can be supplied from a battery or a preregulated supply. The power-up/powerdown controller is configurable and can support any power-up/power-down sequence (programmed in OTP memory). It can be used in (1)Mobile phones and smart phones; (2)Tablets; (3)Gaming handsets; (4)Portable media players; (5)Portable navigation systems; (6)Handheld devices.
