rev. page page date date 1 of 10 04/2011 PART NUMBER: VHB75W DESCRIPTION: half-brick dc-dc converter description The VHB75W series of DC-DC converters are designed for high reliability applications, featuring over-temperature protection, over-current protection. The wide 4:1 input range (9-36V or 18-75V) is very useful to stabilize an input source like batteries in various discharging and charging conditions. Additionally, high efficiency, fast response, tight regulations, remote sense and remote On/Off control make these converters very useful in many applications. features ·37.5-75W isolated output ·Efficiency to 85% ·300 kHz switching frequency ·regulated output ·continuous short circuit protection ·industry standard half-brick size ·remote on/off ·over-temperature protection ·over-current protection M ODEL VHB75W-Q24-S3R3 VHB75W-Q24-S5 VHB75W-Q24-S12 VHB75W-Q24-S15 VHB75W-Q24-S24 VHB75W-Q24-S48 VHB75W-Q48-S3R3 VHB75W-Q48-S5 VHB75W-Q48-S12 VHB75W-Q48-S15 VHB75W-Q48-S24 VHB75W-Q48-S48 notes: input voltage nominal range (V dc) (V dc) output voltage (V dc) output current 1 (A) input current no load 2 full load 2 (mA) (mA) efficiency typ. 3 (%) 24 24 24 24 24 24 48 48 48 48 48 48 9.0~36.0 9.0~36.0 9.0~36.0 9.0~36.0 9.0~36.0 9.0~36.0 18.0~75.0 18.0~75.0 18.0~75.0 18.0~75.0 18.0~75.0 18.0~75.0 3.3 5 12 15 24 48 3.3 5 12 15 24 48 15 15 6.25 5 3.12 1.56 15 15 6.25 5 3.12 1.56 50 50 50 50 50 50 50 50 50 50 50 50 2611 3811 3765 3720 3720 3811 1320 1905 1860 1860 1860 1860 79 82 83 84 84 82 80 83 84 85 85 84 1. see output derating (page 4) 2. input currents are measured at nominal input voltage 3. efficiency is measured at nominal line, full load I NPUT parameter input voltage range under voltage lockout conditions/description min 9 18 nom 24 48 8.8 8 17 16 max 36 75 units V dc V dc V dc V dc V dc V dc remote on/off control 4 input filter notes: 24 Vin power up 24 Vin power down 48 Vin power up 48 Vin power down section 15 in the application notes PI type 4. add suffix “N” to the model number for negative logic on/off control *V-Infinity reserves the right to make changes to its products or to discontinue any product or service without notice, and to advise customers to verify the most up-todate product information before placing orders.
