The Gen2.1 SupIRBuck family incorporates IR's latest advancements in control IC, MOSFET, and package integration technologies to deliver up to 12A of output current in a low-profile, thermally enhanced 5 x 6 mm Power QFN package. This new family of integrated voltage regulators, capable of handling input voltages from 1.5V to 16V, is designed to deliver output voltages from 0.7V to 90% of the input voltage with a new benchmark in efficiency across the entire load range and peak efficiencies exceeding 96%. With programmable switching frequencies up to 1.5MHz, these devices minimize board size while achieving high power density.
The Gen2.1 family eliminates the need for traditional two-stage POL conversion by operating directly from 12V. While optimized for a 12V input voltage, they also achieve superior efficiencies in applications with input voltages of 9.6V, 5V, or 3.3V. In addition to providing pin-compatible current options from 2A to 12A, Gen2.1 SupIRBuck devices offer a new Power Good Output Window (PGOOD) comparator for overvoltage and undervoltage detection, shorter dead time to reduce power losses, and a more precise overcurrent (OC) limit.
Other added features include a 0.7V reference voltage with 1% accuracy, programmable peak current limit, programmable soft start, improved pre-polarization start, thermal protection, enable pin with voltage monitoring capability, sequential control (IR384xW), DDR memory tracking (IR383xW), and an operating junction temperature (Tj) of -40 to 125ºC.
