3 Description

The TPS657095 is a power management unit targeted for embedded camera modules or other portable low power consumer end equipments. It contains two LDOs enabled by the I2C™ Interface, a PWM-dimmable current sink for driving one LED, one general purpose output (GPO), a programmable clock generator and 4K Byte of User OTP memory. The operation of the device is disabled if the input voltage supply is below the internal undervoltage lockout.

The device comes in a 16-ball die-size ball grid array package (DSBGA) with 0.4mm ball pitch.
