Dual Channel Controller With Wide Input Voltage Range

The TL1451A incorporates on a single monolithic chip all the functions required in the construction of two pulse-width-modulation (PWM) control circuits. Designed primarily for power-supply control, the TL1451A 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 1.04 V to 1.45 V. The dead-time control (DTC) Comparator has no offset unless externally altered and CAN provide 0% to 100% dead time. The on-chip Oscillator CAN be operated by terminating RT and CT. During low VCC conditions, the undervoltage lockout control circuit feature locks the outputs off until the internal circuitry is operational.
The TL1451AC is characterized for operation from -20C to 85C. The TL1451AQ is characterized for operation from -40C to 125C. The TL1451AM is characterized for operation from -55C to 125C.
