UNISONIC TECHNOLOGIES CO., LTD TL5001 PULSE-WIDTH-MODULATION CONTROL CIRCUITS DESCRIPTION The UTC TL5001 incorporates on a single monolithic chip all the functions required for a pulse width modulation (PWM) control circuit. Designed primarily for power-supply control, It 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 error-amplifier common-mode voltage ranges from 0V to 1.5V. The noninverting input of the error amplifier is connected to a 1-V reference. Dead-time control (DTC) can be set to provide 0% to 100% dead time by connecting an external resistor between DTC and GND. The oscillator frequency is set by terminating RT with an external resistor to GND. During low Vcc conditions, the UVLO circuit turns the output off until Vcc recovers to its normal operating range.
