TC18C43 Description
The TC38C43 is a current mode BiCMOS PWM control IC. With a low 1.0 mA supply current along with high drive current (0.7A peak) it provides a low cost solution for a PWM that operates to 500 kHz and directly drives MOSFETs up to HEX 3 size. Performance of the oscillator and current sense amplifier have been greatly improved over previous bipolar versions.
