4 Channel Power Management IC (PMIC) in Small Chipscale - TPS65708


4 Channel Power Management IC (PMIC) in Small Chipscale


The TPS65708 device is a power management unit targeted for embedded camera modules or other portable low-power consumer end equipment. The device contains two high-efficiency step-down converters, two low-dropout linear regulators, and a 7.5-mA current sink for driving a LED. The 2.25-MHz step-down converter enters a low-power mode at light load for maximum efficiency across the widest possible range of load currents. For low-noise applications, the devices can be forced into fixed-frequency PWM mode using the MODE pin. The device allows the use of small inductors and capacitors to achieve a small solution size. The TPS65708 device provides an output current of up to 400 mA on both DC-DC converters and up to 200 mA on each of the LDOs. The enable signal to the DC-DC converters and LDOs is generated internally by the undervoltage lockout circuit.

The TPS65708 comes in a small 16-pin wafer chip-scale package (WCSP) with 0.5-mm ball pitch.
