General Description

TS2509 is step-down switching regulator with PWM control and with build in internal PMOS. TS2509 provides low-

ripple power, high efficiency, and excellent transient characteristics. The PWM control circuit can be duty ratio linearly

form 0 up to 100%. This converter also contains an error amplifier circuit as well as a soft-start circuit that prevents

overshoot at startup.

An enable, over current protect and short circuit protect functions are built inside. When OCP or SCP activated, the

operation frequency will be reduced. The internal compensation block is built in to minimum external components and

internal PMOS is complete 3A step down switching regulator ideally for portable devices with outstanding features as

low current consumption.
