STR-A6159 Datasheet, PDF (1/25 Pages) Sanken electric – Off-Line PRC Controllers with Integrated Power MOSFET
Off-Line PRC Controllers with Integrated Power MOSFET
STR-A6100 Series
General Descriptions
The STR-A6100 series are power ICs for switching
power supplies, incorporating a MOSFET and a current
mode PRC controller IC.
PRC (Pulse Ratio Control) controls on-time with
fixed off-time.
The IC includes a startup circuit and a standby
function to achieve the low standby power. The rich set
of protection features helps to realize low component
counts, and high performance-to-cost power supply.

(1) The EI-16 core of transformer is assumed. The output
power is based on the thermal ratings, and the peak output
power can be 120 to 140 % of the value stated here. At low
output voltage, small core and short ON Duty, the output
power may be less than the value stated here.

(3) AC120V
Applications
 White goods
 Auxiliary SMPS
 Low power SMPS, etc.
