The modules use a SMD or SIP package for ease of layout and space savings. The output is closely regulated and the efficiency is typically 90% at full load. Part Selection Output Voltage Input Voltage Max. Output Current Max. Output Power Typical Efficiency Part Number Surface Mount Part Number Vertical Mount 5.0 Vdc 3.0 Vdc - 3.6 Vdc 3 A 15 W 90% SRAH-03C500 VRAH-03C500 Notes: 1. Add “0” suffix at the end of the model number to indicate “Tube Packaging”, and “R” for “Reel Packaging”, and “G” for “Tray Packaging”. 2. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers. Absolute Maximum Ratings Parameter Min Typ Max Notes Input Voltage (continuous) 2.8 V - 4.0 V Ambient Temperature 0 °C - 70 °C Storage Temperature -40 °C - 125 °C Input Specifications Parameter Min Typ Max Notes Input Voltage 3.0 V - 3.6 V Input Current - - 6.3 A Input Reflected Ripple Current (rms) - 30 mA 60 mA Input Reflected Ripple Current (pk-pk) - 100 mA 150 mA With simulated source impedance of 500 nH, 5 Hz to 20 MHz; Use one 270 uF/16 V capacitor with ESR = 0.018 ohm max. at 100KHz at 25 °C.
