General Description

The TS2581 integrates Pulse-Width-Modulation (PWM) control circuit into a single chip, mainly designs for power-

supply regulator. All the functions include an error amplifier, a soft-start, UVLO, OVP, SCP, TSD circuitry.

This device features an internal 100KHz oscillator, the UVLO makes sure that the outputs are off until the internal

circuit operates normally.
