Improved performance and easier design for multi-phase regulators

NXP Semiconductors has introduced the PIP212-12M, a monolithic powertrain IC that eliminates many of the design challenges surrounding synchronous buck converters.

Multi-phase converters are now easier to build, using one PIP212-12M per phase, a single PWM controller, and minimal external passives.

Designed for operating frequencies up to 1MHz and output current up to 35A per phase, the PIP212-12M enables higher power density and easier PCB layout than a discrete solution. A 70A, dual-phase POL converter can be built within a footprint of 7.6cm x 7.6cm, to power advanced microprocessors, high-current DSPs, DDR memory systems and ASICs.

The control MOSFET, synchronous-rectifier MOSFET with parallel Schottky diode, MOSFET driver and bootstrap diode are all included.

This reduces parasitic effects and contributes to achieving 94% peak efficiency at 500kHz. A synchronised 5V source is also integrated, which can supply the external PWM controller in multi-phase designs.

Additional functions include overtemperature protection and power sequencing, as well as automatic dead-time reduction to minimise losses while preventing damaging cross-conduction.
