STR-A6100 Series PRC, Auto Burst Standby, Current-Mode Control Newuct Newuct d Pro d Pro Low Power Off-line SMPS Primary Switcher Features Ratio Control〕 (8 µs fixed off-time, variable on-time) : The switching frequency varies within an optimum range of 63kHz to 120kHz, according to load variations, to create a quasi-jittering, low-EMI noise operation. ● Auto burst standby: (No Load Consumption < 100 mW at AC 264V) Enables very low power consumption at no load. Typical results of a 5W universal input power supply are 35mW at AC110V and 43mW at AC220V. ● Auto bias function This function stabilizes operation during Auto Burst Standby mode, by preventing a Hiccup mode. The Auto Bias function forces the IC to turn on before the VCC voltage reaches VCC (OFF) , thereby stabilizing the entire power supply operation. ● Integrated startup circuit 600 V BCD process allows direct connection of the STARTUP pin to the rectified high voltage rail. This reduces component count and improves overall efficiency. ● Current mode control ● Leading edge blanking Not required the external Low-pass filter circuit which prevent the malfunction due to the leading edge spike current. ● Avalanche energy guaranteed MOSFET with high VDSS The built-in power MOSFET simplifies the surge absorption circuit since the MOSFET guarantees the avalanche energy. No VDSS de-rating is required. ● Various protecting functions • Over current protection ------------ pulse by pulse • Over voltage protection ------------ with latch • Overload protection ---------------- Auto restart • Thermal shutdown ------------------ with latch ● PRC Pulse 〔 Package (DIP-8) Outline (TOP VIEW) Startup 5 4 3 VFB/OLP GND VCC S/OCP Drain Drain 7 8 2 1 Applications Battery Charger ---------------------Standby Power Supply --------------S.M.P.S. -------------------------------Controller Power Supply -----------Cell Phone, Digital Still Camera, Camcorder, Shaver, Emergency light, Guidance light, and etc. Various TV applications, PC, LBP, Audio system and etc. Ink jet printer, DVD Player/ Recorder, VCR, Set Top Box and etc. Air conditioner, Refrigerator, Washer, Dish Washer and etc. Product Lineup Part Number VDSS 500V RDS(ON) 3.95Ω 2.62Ω 1.90Ω 650V 800V 3.95Ω 6.00Ω 19.20Ω VIN(AC) 100V/120V 100V/120V 230V/85V∼264V 230V/85V∼264V 230V/85V∼264V 230V/85V∼264V Pout 12W 16W 24W/20W 16W/12W 13W/10W 8W/5W STR-A6131 STR-A6132 STR-A6153E STR-A6151 STR-A6159 STR-A6169 STR-A6100 Series ■ Design example (STR-A6159) F1 L1 C1 D1 + C2 400V 22µF 1000pF 630V C91 100kΩ R91 SFPB-76 D11 PC1 PC123 R11 220Ω R12 1.5kΩ 50V 0.1µF C13 27kΩ R14 + (5W Universal input-single output power supply) L2 ＋5V/1A AC85∼264V D91 EG01C C11 10V 470µF + C12 10V 220µF IC2 TL431 8 D 7 D 5 Start up EG01Z D2 + C4 35V 22µF T1 EI-16 27kΩ R15 GND IC1 STR-A6159 OCP VCC GND FB 1 2 3 4 4700pF 50V C3 + R3 2.2Ω RD5.1 D3 C5 PC1 PC123 50V 2.2µF 2200pF 250V C99 ■ Electrical Characteristics of the above power supply design Efficiency η vs Output Current IO 100 90 80 0.7 0.6 AC85V AC110V AC220V AC264V Input Power Pin vs Output Power PO Input Power Pin (W) 1.0 Efficiency η(%) 70 60 50 40 30 20 10 0 0.0 0.2 0.4 0.6 0.8 AC85V AC110V AC220V AC264V 0.5 0.4 0.3 0.2 0.1 0.0 0.0 0.1 0.2 0.3 0.4 Output Current IO (A) Output Power PO (W) CAUTION / WARNING Sanken reserves the right to make changes without further notice to any products herein in the interest of improvements in the performance, reliability, or manufacturability of its products.
