The TL5001 and TL5001A incorporate on a single monolithic chip all the functions required for a pulse-width-modulation (PWM) control circuit。 Designed primarily for power-supply control， the TL5001/A contains an error amplifier， a regulator，an oscillator， a PWM comparator with a dead-time-control input，undervoltage lockout (UVLO)， short-circuit protection (SCP)， and an open-collector output transistor。 The TL5001A has a typical reference voltage tolerance of ±3% compared to ±5% for the TL5001。
