TL1453C is a dual pulse-width-modulation control circuit with complete PWM power control circuitry, completely synchronized operation, internal undervoltage lockout protection, wide supply voltage range, 500 kHz oscillator frequency, variable dead time control, and internal stable 2.5V reference supply.
The TL1453C is a dual pulse-width-modulation control circuit designed primarily for power supply control. It integrates two error amplifiers, an adjustable oscillator, two dead-time comparators, and undervoltage lockout circuitry on a single monolithic chip. The device includes an on-chip 2.5-V regulator and uncommitted output transistors providing common-emitter output capability.
