Product Summary

The SI9110DY is a BiC/DMOS integrated circuit designed for use as high-performance switchmode controllers. A high-voltage DMOS input allows the controller to work over a wide range of input voltages (10- to 120-VDC). Current-mode PWM control circuitry is implemented in CMOS to reduce internal power consumption to less than 10 mW.

Parametrics

SI9110DY absolute maximum ratings: (1)Voltages Referenced to -VIN, VCC: 15 V; +VIN: 120 V; (2)Logic Inputs (RESET, SHUTDOWN, OSC IN, OSC OUT): -0.3 V to VCC + 0.3 V; (3)Linear Inputs (FEEDBACK, SENSE, BIAS, VREF): -0.3 V to VCC + 0.3 V; (4)HV Pre-Regulator Input Current (continuous): 5 mA; (5)Storage Temperature: -65 to 150℃; (6)Operating Temperature -40 to 85℃; (7)Junction Temperature (TJ): 150℃℃; (8)Power Dissipation: 750 mW.

Features

SI9110DY features: (1)10- to 120-V Input Range; (2)Current-Mode Control; (3)High-Speed, Source-Sink Output Drive; (4)High Efficiency Operation (> 80%); (5)Internal Start-Up Circuit; (6)Internal Oscillator (1 MHz); (7)SHUTDOWN and RESET; (8)Reference Selection ±1%.
