description
The TL5002 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 TL5002 contains an error amplifier, a
regulator, an oscillator, a PWM comparator with a dead-time-control input, undervoltage lockout (UVLO), and
an open-collector output transistor.
The error-amplifier input common-mode voltage ranges from 0.9 V to 1.5 V. 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 TL5002 is characterized for operation from −40°C to 85°C.
