ISL83202IBZ Typical application Circuitry

ISL83202IBZ is a dual-channel synchronous buck DC-DC converter controller chip produced by Intersil (now Renesas Electronics Corporation). This chip is suitable for various application scenarios, including industrial, communication, server, data storage, and other fields.

Parameter Features:

- Input Voltage Range: 4.5V to 28V

- Output Voltage Range: 0.6V to Input Voltage

- Operating Frequency Range: 100kHz to 1MHz

- Supports constant frequency, current mode control

- Adjustable soft start and shutdown time

- Rich protection features: overcurrent protection, overvoltage protection, undervoltage protection, etc.

- Programmable output voltage balance function

- Programmable and monitoring capabilities via I²C interface

Application Scenario Example: High-efficiency server power supply

Circuit Connection Example:

In high-efficiency server power supplies, the ISL83202IBZ is used as a controller for power conversion, converting a high input voltage (such as 24V) into a stable low output voltage (such as 1.8V) for the core components of the server. Below is a detailed circuit connection example, covering the main connection points and some design considerations.

Circuit Connection:

1. Input Power Connection:

- Connect the 24V input power to the VIN pin (Pin 1) of the chip.

- Connect the input ground (GND) to the GND pin (Pin 8) of the chip.

2. Output Voltage Feedback and Setting:

- Connect the output voltage feedback resistor network to the FB pin (Pin 5) and GND pin (Pin 8) to achieve output voltage feedback and regulation.

3. Output Voltage Setting:

- Program the chip via the I²C interface (SDA and SCL pins) to set the desired output voltage and other parameters. For instance, the output voltage can be adjusted using I²C commands.

4. Output Current Sensing:

- Connect the output current sensing resistor to the CSS pin (Pin 4) of the chip to monitor the output current.

5. Switch FET Driving:

- Connect the gate driving signals of the switch FET to the HO and LO pins (Pins 2 and 3) of the chip to control the power switch.

6. Synchronous Rectification FET Driving:

- If synchronous rectification is used, connect the gate driving signals of the synchronous rectification FET to the HS and LS pins.

7. Power Management and Monitoring:

- Through the I²C interface, monitor the chip to obtain real-time information about voltage, current, temperature, etc.

Design Considerations:

When designing this circuit, the following issues should be considered:

- Stability and Ripple: Ensure stable output voltage and control ripple within an acceptable range.

- Efficiency: Optimize switching frequency and selection of inductors/capacitors to improve conversion efficiency.

- Heat Management: Consider chip power dissipation and heat dissipation, choosing appropriate heat dissipation measures.

- Protection Features: Configure suitable protection features to ensure safe shutdown in case of faults.

- EMI (Electromagnetic Interference): Take measures to reduce electromagnetic interference to comply with relevant standards.

- Filtering and Wiring: Use filtering capacitors and inductors in input and output circuits to reduce noise.

- PCB Layout: Design a well-organized PCB layout to minimize signal interference and loop instability.

Through effective circuit design, ISL83202IBZ can provide reliable power conversion functionality in applications like high-efficiency server power supplies, while meeting stability, efficiency, and protection requirements.
