Product Details

The MAX15492 is a synchronous half-bridge driver with ultra-low-power mode. The device is intended to work with controller ICs such as the MAX15411, MAX15566/MAX15567, or MAX15576/MAX15577 in multiphase CPU core regulators. To provide the best light-load efficiency, the controller can place the device into an ultra-low power mode where the supply current is only 4µA.

The low-side driver is optimized to drive 3nF capacitive loads with 3ns/7ns typical fall/rise times, and the high-side driver with 7ns/14ns typical fall/rise times. Adaptive dead-time control prevents shoot-through currents and maximizes converter efficiency.

The MAX15492 is available in a small, 8-pin (2mm × 2mm) TDFN package with an exposed pad.
