The “A” versions provide a • Low power consumption full 3A of gate drive while the “B” and “C” versions provide 2A and 1A respectively. The outputs are • Pin compatible with HIP2100/HIP2101 independently controlled with TTL input thresholds. An integrated high voltage diode is provided to TYPICAL APPLICATIONS charge the high-side gate drive bootstrap capacitor. A • Motor controlled drivers robust level shifter operates at high speed while consuming low power and providing clean level • Half and Full Bridge power converters transitions from the control logic to the high-side gate • Synchronous buck converters driver. Under-voltage lockout is provided on both the • Two switch forward power converters low-side and the high-side power rails. These devices • Forward with Active Clamp converters are available in the standard SOIC-8 pin, SO Power Pad-8, WSON-8 (4 mm x 4 mm), WSON-10 (4 mm x • 48V server power 4 mm), and MSOP Power Pad-8 packages. • Solar DC/DC and DC/AC converters SIMPLIFIED BLOCK DIAGRAM 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
