Description The RP75-SB Series has been specifically designed for low voltage silicon applications. A wide input voltage range, output voltage trim and sense inputs are all standard features. The converters also benefit from comprehensive over-current, over-voltage and over-temperature protection. The RP75-SB is ideally suited to telecom, network and industrial applications. Notes: 1. Maximum output deviation is 10% inclusive of remote sense. If remote sense is not being used, the +Vsense should be connected to its corresponding +Vout 2. The pin voltage is referenced to negative input. 3. Heat sink is optional and P/N: 7G-0021, 7G-0022, 7G-0023, 7G-0024. 4. The RP75-SB meets level A and level B conducted emissions only with external components connected before the input pin to the converter. 5. Typical value at nominal input voltage and full load. 6. BASEPLATE GROUNDING : Base-plate should be grounded at one of the four screw bolts prior to operation. www.recom-international.com July-2006 191 RP75-SB Series INNOLINE DC/DC-Converter Specifications (refer to the standard application circuit, Ta: 25°C) Input Voltage Range Under-Voltage Lockout 36-75VDC Power Up Power Down Input Filter Input Surge Voltage 100ms max Start up time Remote ON/OFF (Note 2) (Positive logic) (Negative logic) L-C type 100VDC Nominal Vin and constant resistive load ON=Open or 3.0V < Vr < 15V, OFF=Short or 0V < Vr < 1.2V, ON=Short or 0V < Vr < 1.2V, OFF=Open or 3.0V < Vr < 15V, Continuous Output Power Output Voltage Accuracy Full load and nominal Vin ±1.5% 0% Line Regulation low line to high line at full load Load Regulation 0% to 100% full load Remote Sense (Note 1) ±0.2% See table 10% of Vout With 10µF tantalum and 1µF ceramic across Output Temperature Coefficient 100mVp-p ±0.02%/ºC 25% load step change Over Voltage Protection threshold (Hiccup) 200µs 120% of Vout Over Current Protection threshold 110% ~ 140% of Iout Rated Short Circuit Protection Efficiency (at nominal input voltage, full load) Isolation Voltage IIN=1mA max.
