Power supplies GENERAL DESCRIPTION
The ADuM52301 is an isolated half-bridge gate driver that In comparison to gate drivers employing high voltage level employs Analog Devices, Inc., iCoupler® technology to provide translation methodologies, the ADuM5230 offers the benefit independent and isolated high-side and low-side outputs. of true, galvanic isolation between the input and each output. Combining CMOS and microtransformer technologies, this Each output can operate up to ±700 VP relative to the input, isolation component contains an integrated dc-to-dc converter thereby supporting low-side switching to negative voltages. providing an isolated high-side supply. This eliminates the cost, The differential voltage between the high side and low side space, and performance difficulties associated with external may be as high as 700 VP. supply configurations such as bootstrap circuitry. This high- side isolated supply powers not only the ADuM5230 high-side output but also any external buffer circuitry used with the ADuM5230. 1 Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; 7,075,329; other pending patents.
