TS2508 - 3A / 330KHz PWM Buck Converter

General Description

TS2508 consists of step-down switching regulator with PWM control.

These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc.

TS2508 provides low-ripple power, high efficiency, and excellent transient characteristics.

Key Features

TS2508 2A / 330KHz PWM Buck Converter SOP-8 Pin Definition: 1. FB 8. Vss 2. Enable 7. Vss 3. Ocset 6. SW 4. Vcc 5. SW General Description TS2508 consists of step-down switching regulator with PWM control. These devise include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc. TS2508 provides low-ripple power, high efficiency, and excellent transient characteristics. The PWM control circuit is able to very 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 protect function are built inside, and when OCP or SCP happens, the operation frequency will be reduced.
