TS1451

The TS1451 integrates dual channel PWM control circuit into a single chip, mainly designs for power supply regulator. All the functions included an on-chip 2.5V reference output, two error amplifiers, and adjustable oscillator, two dead-time comparators, under voltage lock out, short circuit protection, and dual common-emitter output transistor circuit.

Recommend the output CE transistors of the TS1451 as pre-driver for driving extremely. the dead time control can provide from 0% to 100%. Switching frequency can be adjustable by trimming RT and CT. During low Vcc situation, the under voltage lock out makes sure that the output are off until the internal circuit is operational normally.   The TS1451 is offered in SOP-16 and DIP-16 package.
