TS1451 Dual Channel PWM Controller SOP-16 DIP-16 Supply Voltage Range 3.6 V to 40V Output Driving Current 20mA Oscillator Frequency up to 500KHz General Description 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 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.
