The RVP6501 transformer driver integrated circuit operates with a supply voltage of 2.8 V to 6 V DC, but can withstand transient surges of 10 V without damage. It delivers 500 mA across the entire input voltage range, exceeding the 6501-type specification of 300 mA at 5 V and 150 mA at 3.3 V. Like the 6501-type, it features open-before-close switching, but unlike the original, it senses gate driver voltages to adaptively adjust dead-time spacing to automatically compensate for any thermal, load current, and aging drift in the gate threshold voltage. Furthermore, the RVP6501 monitors transistor current to provide continuous protection against short circuits and overloads. These two functions of precise circuit breaker timing and overcurrent protection prevent the risk of core saturation due to flux imbalance, one of the main disadvantages of the "push-pull" topology.
“RECOM has been a technology leader in DC/DC modules for over 50 years, a position maintained only through a constant flow of new ideas and continuous improvements in quality, reliability, and performance. The RVP6501 is an enhanced version of the industry-standard 6501-type transformer driver, but it costs considerably less,” says Sven Krumpel, Integrated Circuits and Solutions Project Manager at RECOM.
The parts include a three-year warranty.
