Overview
STR3A151, STR3A152, STR3A153, STR3A154, STR3A155 PWM Off-Line Switching Regulator ICs Features and Benefits • Current mode PWM control • Built-in Random Switching function: reduces EMI noise, simplifies EMI filters, and cuts cost by external part reduction • Built-in Slope Compensation function: avoids subharmonic oscillation • Built-in Leading Edge Blanking (LEB) function • Auto Standby function: ▫ Input power, PIN < 10 mW at no load with low power consumption shunt regulator ▫ Normal load operation: PWM switching ▫ Light load operation: Standby mode (Burst oscillation) Continued on the next page… Package: DIP8 Not to scale Description STR3A100 series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC in one package.
Including a startup circuit and a standby function in the controller, the product achieves low power consumption, low standby power, and high cost-effectiveness in power supply systems, while reducing external components.
The products are provided in an industry standard DIP8 package.
Applications Switching power supplies for electronic devices such as: • Stand-by power supply for LCD/PDP television, desktop PC, multi-function printer, audio equipment, and so forth • Small switched-mode power supply (SMPS) for printer, BD/DVD player, set-top box, and so forth • Auxiliary power supply for air conditioner, refrigerator, washer, dishwasher, and so forth VAC D1 C1 Typical Application CRD Snubber Circuit C9 T1 D4 C5 R3 D3 P S C6 C, RC Damper Snubber Circuit 8 76 5 D/ST D/ST DN/SCT D/ST C4 U1 STR3A100 S/OCP VCC GND FB/OLP 1234 D2 R2 C2 D ROCP C3 PC1 L2 R9 PC1 R4 R8 R5 C7 R6 U2 R7 VOUT C8 GND STR3A150-DS SANKEN ELECTRIC CO.
