Hi all
I think i new chip for smps by use Micro# pic 1220
FEATURES
1. PWM 100kHz AT 55 step and if up to 50 step Pwm=120kHz-150Khz 33-50ms
2. essy 3 Temp senser for tranformer and heaksink
3. essy duty 1-50 step by POT for dc inverter welder
4. essy protec control desing
4. essy power relay drive
5. essy to CHARGE BATTERY MODE
PLS commen |

Excuse me, but the schematic is not really clear to me.... may be someone can understand.
Also, why to use a pic when you can do the same with a 50 cents IC ? |

Can you lead us to an application note or sim so everything is clearer.
