TS2509
General Description
TS2509 consists of step-down switching
regulator with PWM control.
These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc.
TS2509 provides low-ripple power, high efficiency, and excellent transient characteristics.
The PWM control circuit is able to the 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 function, an over current protect function and short circuit pr...
