Description

Description: Input voltage: 3.6~30VOutput voltage:  ±3~±30V adjustableMaximum output power: 20W Conversion efficiency :69-89%Quiescent current: 3-4mAWorking frequency 180KHzOperating temperature : -40 to +85 ? Size : 60 x 34 x 15 mmWeight :  33g Features: - High efficiency up to 89%- Built in Frequency Compensation- Built in Soft-Start Function- Built in Thermal Shutdown Function- Built in Current Limit Function Applications:  ADC/DAC/Operational Amplifier Reference voltageRS232 RS485 RS422 BusAudio equipmentLow power audio power supplyCar audio amplifier dual power boardLCD power supplyInstrumentation equipmentInstrumentation multimeter       Note: 1. In order to obtain a more stable voltage, it is recommended that the output is greater than 15MA.2. V- cannot be used alone, or no voltage output.But you can just use V+ .3. The startup current of the module is 2.5-3 times the operating current.4. Increasing the 1UF-10UF MLCC capacitor reduces the startup current.      The maximum output power can reach 20W, but the maximum power will vary under different conditions. For details, please refer to the following table(10-80% of the maximum power is the most reliable):5V/±5V Output
