DESCRIPTION

· The TS2581 integrates a Pulse-Width-Modulation (PWM) control circuit into a single chip, primarily designed for power-supply regulation.

· It includes an error amplifier, soft-start, UVLO, OVP, SCP, and TSD circuitry.

· The device features an internal 100KHz oscillator, with UVLO ensuring outputs remain off until the internal circuit operates normally.

FEATURES

· Input voltage range: 8V to 40V.

· Duty ratio: 0% to 100% PWM control.

· Oscillation frequency: 100K/300KHz.

· Thermal Shutdown function.

· Short Circuit Protect (SCP).

· External SW P-channel MOS.

· External OVP setting function.

· Current mode non-synchronous PWM converter.

· External current limit setting.

· Under voltage Lockout.

APPLICATIONS

· Simple High-efficiency Step down Regulator.

· Charger.

· Telecommunication.
