TL1451A Description

Short technical summary and product information.

The TL1451A from Texas Instruments is a complete PWM power control circuitry solution integrated onto a single monolithic chip. It is designed for power-supply control applications and offers completely synchronized operation.

 

Key electrical specifications include a wide supply voltage range from 3.6V to 50V, a maximum oscillator frequency of 500 kHz, and a typical quiescent current of 0.0017A. The device also features an internal 2.5-V reference supply, providing stability for control operations. The operating temperature range is from -40°C to 125°C, making it suitable for demanding environments.

 

This controller incorporates internal undervoltage lockout protection and internal short-circuit protection for enhanced reliability. The uncommitted output transistors provide common-emitter output capability for each controller. The dead-time control (DTC) comparator allows for 0% to 100% dead time control.

 

The TL1451A is available in a 16-pin TSSOP package with dimensions of 5 mm x 6.4 mm, offering a package area of 32 mm². It is qualified for automotive applications and is available in Q-Temp automotive high-reliability automotive applications.
