PTH08T221WAD Typical application Circuitry

PTH08T221WAD

The PTH08T221WAD is a high-performance, non-isolated, wide-input voltage range, dual-output power module. It is designed for applications that require efficient power conversion to supply two different voltage levels simultaneously from a single input.

Application Scenario: Dual-Voltage Power Supply for an Embedded System with CPU and I/O Interfaces

Introduction: In this application, the PTH08T221WAD is employed to provide power to a central processing unit (CPU) and the input/output (I/O) interfaces of an embedded system, ensuring that both components receive their required voltage levels for optimal performance.

Key Parameters and Features:

- Wide Input Voltage Range: This feature allows the module to operate across various power environments, accommodating input voltage fluctuations.

- Dual Adjustable Outputs: Enables precise adjustment of two different output voltages to meet the specific requirements of the CPU and I/O interfaces.

- High Efficiency: Essential for reducing power loss and heat generation, thereby enhancing the overall reliability and performance of the embedded system.

- Compact Design: The module's small footprint facilitates integration into space-constrained embedded systems without compromising power delivery or system design.

- Protection Features: Over-temperature protection, under-voltage lockout, and over-current protection mechanisms safeguard the system components from potential power-related issues.

Detailed Circuit Connection:

- Connecting to the Power Source: Attach the "VIN" pin of the PTH08T221WAD to the embedded system's main power supply, ensuring the voltage is within the module's operating range for efficient performance.

- First Output Voltage Adjustment for the CPU: Utilize a resistor divider from the first "VOUT" pin to the "TRIM1" pin, with the other end connected to "GND." Determine the resistor values needed to provide the CPU with the output voltage that the datasheet specifies.

- Second Output Voltage Adjustment for I/O Interfaces: Establish a second resistor divider from the second "VOUT" pin to the "TRIM2" pin, also connected to "GND," to set the output voltage required by the I/O interfaces. Determine resistor values based on the datasheet's guidelines for the targeted voltage.

- Powering the CPU and I/O Interfaces: Directly connect the first "VOUT" pin to the CPU's power input and the second "VOUT" pin to the power inputs of the I/O interfaces. Ensure the module's total output current capacity is not exceeded by the combined demands.

- Grounding: Firmly attach the embedded system's ground plane to the "GND" pin. Stable operation and the reduction of electrical noise depend on effective grounding.

Design Points to Remember:

- Thermal Management: Consider implementing cooling solutions for the PTH08T221WAD, particularly when operating at high output currents or in environments with elevated temperatures.

- Input Voltage Stability: Stabilize the input voltage to the module to maintain consistent output voltages, critical for the reliable operation of the CPU and I/O interfaces.

- Load Variability: Account for changes in the power consumption of the CPU and I/O interfaces, ensuring that the power supply design can adapt to variations in load without affecting voltage stability or efficiency.

By carefully integrating the PTH08T221WAD into an embedded system to supply power to the CPU and I/O interfaces, designers can create a reliable, efficient, and precise dual-output power solution that supports the critical functions of the system.
