The is a 125V/2A, high speed, half-bridge MOSFET driver in 12 pin TQFN package. The high-frequency, 125V half-bridge, N-channel MOSFET drivers drive high and low-side MOSFETs in high voltage applications. Driver is independently controlled and its 35ns typical propagation delay from input to output are matched to within 3ns typ. The high voltage operation with very low and matched propagation delay between drivers and high source/sink current capabilities in a thermally enhanced package make this device suitable for high power, high frequency telecom power converters. The 125V maximum input voltage range provides plenty of margin over 100V input transient requirement of telecom standards. A reliable on-chip bootstrap diode connected between VDD and BST eliminates need for an external discrete diode. This device is used in telecom half-bridge power supplies, two switch forward converters, full-bridge converters, active-clamp forward converters and power supply module.
