TPS65708,pdf(PMU for Embedded

TPS65708 is a power management unit targeted for embedded camera module or other portable low power consumer end equipments. It contains two high efficient step down converters, two low dropout linear regulators and a 7.5mA current sink for driving a LED. The 2.25MHz 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. TPS65708 provides an output current of up to 400mA on both DCDC converters and up to 200mA on each of the LDOs. The enable signal to the dcdc converters and LDOs is generated internally by the undervoltage lockout circuit.
