Product catalog summary

Product Overview
The FD25-XXSXXB3(C)(-T)(-TS) Series is a DC/DC Converter designed by Guangzhou Aipu Electron Technology Co., Ltd. It features a wide input voltage range (4:1) and delivers an output power of 25W. The converter is housed in an ultrathin package of 9.5mm and boasts a transfer efficiency of up to 90%. It includes protections against input under-voltage, output over-voltage, short circuit, and over-current, with a switching frequency of 350KHz and an isolation voltage of 1500VDC. The operating temperature range is -40°C to +85°C.

Input Specifications
The converter can handle input surge voltages of up to 50VDC for 24V inputs and 100VDC for 48V inputs. It features a start-up time of 5ms and uses a Pi filter for input filtering. The control pin (CTRL) allows for module turn-on and turn-off, with specific voltage requirements for each state.

Output Specifications
Output voltage accuracy is within ±2.0%, with line voltage regulation at ±1.0%. Load regulation is maintained at ±2.0% from 10% to 100% nominal load. The converter includes output over-voltage protection (110%-200%Vo) and output short circuit protection with self-recovery. Dynamic response to load changes is specified as ≤±5.0%/500μs.

General Specifications
The converter operates at a typical switching frequency of 350KHz and has an isolation capacitor of 2000pF. It is designed to function within a temperature range of -40°C to +85°C, with a maximum case temperature of +105°C. The product weight is approximately 28g.

EMC Characteristics
The converter meets EMC standards with external circuits required for compliance with CISPR22/EN55022 CLASS B for EMI and various IEC/EN61000 standards for EMS.

Package and Dimensions
The B3 package dimensions are 50.80X25.40X9.5mm, with variations for chassis and DIN-Rail mounting. Pin functions include +Vin, -Vin, CTRL, Trim, -Vo, and +Vo.

Design and Application Reference
Recommended circuits and components are provided for optimal performance, including specific capacitor values for ripple and noise reduction. The document advises maintaining a minimum load of 10% to prevent increased output ripple.
