Designed primarily for power supply control, the TL1453C contains an on-chip 2.5-V regulator, two error amplifiers, an adjustable oscillator, two dead-time comparators, undervoltage lockout circuitry, and dual common-emitter output transistor circuits. The uncommitted output transistors provide common-emitter output capability for each controller. The internal amplifiers exhibit a common-mode voltage range from 1.05 V to 1.45 V. The dead-time control comparator has no offset unless externally altered and may be used to provide 0% to 100% dead time. The on-chip oscillator may be operated by terminating RT (pin 2) and CT (pin 1). During low-VCC conditions, the undervoltage lockout control circuit feature inhibits the output until the internal circuitry is operational. The TL1453C is characterized for operation from –20°C to 85°C. functional block diagram CT 1 VCC 9 REF 1 IN+ 1 IN– 1 FEEDBACK 2 FEEDBACK 2 IN+ 2 IN– Vref = 2.5 V 16 3 Error Amp.1 Reference Voltage 2.5 V RT 2 Triangle Oscillator 2V 1.4 V PWM Comparator 1 7 1 OUTPUT 4 1 5 12 Error Amp.2 14 10 13 2 OUTPUT 2.5 V 2 2.5 V SCP 15 † UVLO = Undervoltage Lockout Protection PWM Comparator 2 UVLO† 6 1 DEAD-TIME CONTROL 8 GND 11 2 DEAD-TIME CONTROL Copyright  1990, Texas Instruments Incorporated PRODUCTION DATA information is current as of publication date.
