The LM72630-Q1 is a 70V, synchronous buck converter with constant-current constant-voltage (CC-CV) regulation and I2C interface. The device is compatible with USB Type-C PD controllers including the TPS2674X-Q1 family.

The converter uses a peak current-mode control architecture for easy loop compensation, fast transient response, and excellent load and line regulation. The highly accurate CC-CV operation enables seamless transition between constant-current and constant-voltage modes. The I2C interface allows programming of output voltage in 10mV or 20mV steps, average output current limit in 50mA steps, as well as output voltage slew rate, switching frequency, soft-start slew rate, mode of operation, current loop compensation, output active discharge strength, and cable drop compensation gain.

The LM72630-Q1 also contains an array of safety features including undervoltage and overvoltage protection with programmable thresholds, overcurrent protection with programmable hiccup mode, and thermal shutdown.

Additional features of the LM72630-Q1 include programmable diode emulation for lower current consumption at light-load conditions, open-drain nINT flag for fault reporting and output monitoring, precision enable input, monotonic start-up into prebiased load, integrated dual input (VIN and VOUTF) VCC supply regulator, and oversized VDDA regulator for powering external loads, such as companion USB PD controllers.

The LM72630-Q1 converter comes in a 6mm × 6mm thermally-optimized, 29-pin VQFN package. The three die-attach pads (VIN, SW, and PGND) improve thermal performance and board level reliability (BLR).

The LM72630-Q1 converter belongs to a family of synchronous buck converters with constant-current constant-voltage (CC-CV) regulation and I2C interface listed in Related Products.
