Details

Si9113 is a current mode PWM controller for ISDN power supplies. In a 14-pin SOIC package, it provides all necessary functions to implement a single-switch PWM with a minimum of external parts. To maximize the circuit integration, the Si9113 is designed with a 200-V depletion mode MOSFET capable of powering directly off the high input bus without an external start-up circuit. The Start and Stop input voltage thresholds can be programmed within the operating input voltage range by means of a resistor divider, provided +VIN (Start)> +VIN (Stop).FEATURES BiC/DMOS Technology Current Mode Control Max 50% Duty Cycle Operation 1.3-MHz Error Amp Up to 500-kHz Internal Oscillator Soft-Start 0.6-V Fast Over-Current Protection <5-µA Supply Current for +VIN <18 V 23.5-V to 200-V Input Voltage Range Programmable Start/Stop Capability Internal Start-Up Circuit Power_Good Output

FAQs

What is SI9110DY?

The SI9110DY is a green-mode PWM controller designed by Vishay Siliconix. It is specifically tailored for use in high-performance offline flyback converters, making it suitable for applications such as power supplies, lighting, and home appliances.

How Does SI9110DY Work?

The SI9110DY operates as a pulse-width modulation (PWM) controller that incorporates green-mode functionality to enhance energy efficiency. It regulates the duty cycle of the output waveform to control the power delivered to the load. The device features protection functions, soft-start capability, and power-saving modes to optimize performance and reliability.

How Many Pins does SI9110DY have and What are the Functions of the Pinout Configuration?

The SI9110DY is housed in a 7-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

VCC: Power supply pin.
GND: Ground pin.
X: Multi-function pin for various control and feedback purposes.
FB: Feedback pin for output voltage regulation.
RT: Timing resistor pin for frequency adjustment.
CS: Current sense pin for overcurrent protection.
OUT: Output pin for driving external components.

What are the Pros and Cons of SI9110DY?

Pros:

Green-Mode Functionality: Enhances energy efficiency and reduces power consumption.
Protection Features: Includes built-in protection functions for reliable operation.
Compact Package: Housed in a space-saving SOIC package for easy PCB integration.
