Texas Instruments Current Mode PWM Controller IC, DIP-8, 15V / 1A Output, 12-25

The Texas Instruments Current Mode PWM Controller IC is a highly optimised component designed for efficient power conversion in a variety of electronic circuits. Engineered for both off-line and DC-to-DC converters, it delivers precise control and reliable performance for demanding power supply applications.

A key advantage of this controller is its low start-up current of less than 0.5mA, which minimises power drain during initialisation. It incorporates automatic feed-forward compensation, enhancing its dynamic response to input voltage changes, and features pulse-by-pulse current limiting for robust overload protection. The integrated enhanced load response characteristics ensure stable output under varying load conditions.

For system safety and reliability, the IC includes an under-voltage lockout with hysteresis, preventing operation at insufficient supply voltages, and double pulse suppression to maintain switching integrity. Its high current totem pole output is capable of directly driving power MOSFETs, simplifying circuit design. The core is built around an internally trimmed bandgap reference and a low RO error amplifier, providing exceptional voltage regulation accuracy.

Housed in a standard 8-pin DIP (Dual In-line Package), it is designed for straightforward through-hole mounting on printed circuit boards. This component is specified as a green product, manufactured without antimony or bromine-based flame retardants (Sb/Br).
