2 / 11 page 3513 CMOS IC UNISONICTECHNOLOGIESCO.,LTD 2 of 11 www.unisonic.com.tw QW-R502-129.B PIN ASSIGNMENT PIN DESCRIPTIONS PIN NO PIN NAME TYPE DESCRIPTION 1 PGI Input Power Good Input. For ATX SMPS, it detects AC line voltage through the main transformer. 2 GND Supply Ground 3 FPOB Output Fault Protection Output. Output signal to control the primary PWM IC through an opto-coupler. When FPOB is low, the PWM IC is enabled. 4 PSONB Input Remote On/Off logic input from CPU or main-board. The power supply will be turned on/off after 38mS delay. 5 OTP/FC Input Over temperature protection/Fan speed control 6 RI Input Reference setting. One external resistor Ri connected between RI and GND pin will determine a reference current, IREF = 1.20/Ri, for OCP programming. 7 VS12B Input 12V over/under voltage protection. 8 IS12B* Input 12V over current protection. 8 PWM** Output Pulse width modulation. 9 IS12A* Input 12V over current protection. 9 IS12AB** Input 12V over current protection. 10 VS12A Input 12V over/under voltage protection. 11 IS33 Input 3.3V over current protection 12 VS33 Input 3.3V over/under voltage protection 13 IS5 Input 5V over current protection. 14 VS5 Input 5V over/under voltage protection. 15 VDD Supply Power supply. 16 PGO Output Power good logic output, 0 or 1(open-drain). Power good=1 means that the power supply is good for operation. The power good delay is 300mS. * 3513E only ** 3513F only |
