The TL5001A incorporates on a single monolithic chip all the functions required for a pulse-width-modulation
(PWM) control circuit. Designed primarily for power-supply control, the TL5001A 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%.
The error-amplifier common-mode voltage ranges from 0 V to 1.5 V. 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.
The TL5001A is characterized for operation from –40°C to 125°C.
