GR8830  
Green-Mode PWM Controller below 100mW Standby Power  
Features  
Description  
Current mode PWM control  
The GR8830 is a highly-integrated, low startup  
current, current mode PWM controller with  
Green-mode function. This function enables the  
power supply to easily meet even the strictest  
power conservation requirements. The integrated  
functions also include the leading-edge blanking  
Standby power below 100mW solution  
Under voltage lockout (UVLO)  
Non-audible-noise green-mode control  
Programmable switching frequency  
Internal leading-edge blanking  
Internal slope compensation  
of  
the current sensing, internal slope  
Internal soft start  
compensation, cycle-by-cycle peak current  
limiting, and soft start. OLP, OCP and OVP  
provide protection performance for fault conditions.  
For protecting the external power MOSFET from  
being damaged by supply over voltage, the  
GR8830 OUT pin voltage is clamped to about  
13V.  
Gate output voltage clamp  
Jitter and soft driving for reducing EMI  
Over-voltage protection (OVP) on VCC pin  
Over-load protection (OLP)  
Over-current protection (OCP) on CS pin  
Over-temperature protection (OTP)  
The GR8830 improves the performance and  
reduces the cost of power supplies. It is with both  
DIP-8 and SOT-26 package.  
Applications  
Switching AC/DC power adaptor  
Battery charger  
Open-frame SMPS  
Ordering and Marking Information  
DIP-8  
SOT-26
