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 87% 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 1.5 A 7.5 W 87% SRAH-02C50x VRAH-02C50x 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. Replace “x” with “0” to allow burst mode operation at low load currents, or with “B” to disable burst mode operation at light loads. Absolute Maximum Ratings Parameter Min Typ Max Notes Input Voltage (continuous) 2.8 V - 4.0 V Ambient Temperature -40 °C - 85 °C Storage Temperature -40 °C - 125 °C Input Specifications Parameter Min Typ Max Notes Input Voltage 3.0 V - 3.6 V Input Current - - 3.3 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 100 kHz I 2t Inrush Current Transient - 0.02 A 2s 0.05 A 2s Turn-on Voltage Threshold - 2.8 V 2.9 V xRAH-02C50x RoHS Compliant |
