THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 PIN CONFIGURATIONS AND ORDERING INFORMATION ORDERING INFORMATION Part Number Temperature Range Package Si9118DY - 40 to 85 °C SOIC-16 Si9118DY-T1 Si9118DY-T1-E3 Si9119DY Si9119DY-T1 Si9119DY-T1-E3 PIN DESCRIPTION Pin Number Symbol Description 1 +VIN Input bus voltage ranging from 10 V to 200 V. 2 PWM/PSM Connected to VREF forces the converter into PWM mode. Connected to -VIN forces the converter into PSM mode. 3 VREF 4 V reference voltage. Decouple with 0.1 µF ceramic capacitor. 4 NI Non-inverting input of an error amplifier. 5 FB Inverting input of an error amplifier. 6 COMP Error amplifier output for external compensation network. 7 SS/EN Programmable soft-start with external capacitor or externally controlled disable mode. 8 COSC External capacitor to determine the switching frequency. 9 ROSC External resistor to determine the switching frequency. 10 ILIMIT Pulse by pulse peak current limiting pin. When the current sense voltage exceeds the current limit threshold, the gate drive signal is terminated. ILIMIT is also used to sense the current in pulse skipping mode. 11 ICS Current sense input to control feedback response. 12 SYNC or VSC Si9118: slope compensation pin. Si9119: clock synchronization pin. Logic high to low transition from external signal synchronizes the internal clock frequency. 13 DMAX Sets the maximum duty cycle. Internally, the maximum duty cycle is clamped to 80 %. 14 -VIN Single point ground. 15 DR Gate drive for the external MOSFET switch. 16 VCC Supply voltage for the IC after the startup transition.
