TS1451  
Dual Channel PWM Controller  
DIP-16  
SOP-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. 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.
