Dual Channel Controller with Wide Input Voltage Range
Oscillator Frequency... 500 kHz Max Variable Dead Time Provides Control Over Total Range Internal Regulator Provides a Stable 2.5-V
Reference Supply
descriptionThe TL1453C incorporates the functions required in the construction of two pulse-width-modulation control
circuits on a single monolithic chip. 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.
