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 ...
