The modules use a SMT package. These converters are available in a range of output voltages from 0.8 Vdc to 3.63 Vdc over a wide range of input voltage (Vin = 6 Vdc - 14 Vdc). The Bel SRBC-30E2AL has a sequencing feature that enables designers to implement various types of output voltage sequencing when powering. The efficiency is typically 92% at 3.3 Vdc output at full load. Part Selection Output Voltage Vo≤ 2.5 V Vo ＞ 2.5 V Input Voltage 6 V - 14 V Max. Output Current 30 A 25 A Max. Output Power 75 W 90 W Typical Efficiency 87% 92% Model Number Active Low SRBC-30E2AL Note: Add “G” suffix at the end of the model number to indicate Tray Packaging.
