Product Summary
The TL1453CPWR is a dual pulse-width-modulation control circuit. The TL1453CPWR 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 TL1453CPWR 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.
