4 x 4 x 0.6mm measuring 4 Amps PoL voltage regulator chip from Semtech

Semtech Corp. has announced a small size new dual-channel buck type voltage regulator IC,the SC286 for point-of-load (POL) applications. Semtech says SC286 can further simplifies power supply design by integrating the regulator, loop compensation components, power MOSFETs and MOSFET drivers on one chip and eliminates the need for external loop stabilization components and programming resistors, making component selection and layout much easier, while contributing to the small design footprint. Designers can use this SC286 regulators in applications such as analog-to-digital converters, microcontrollers, DSPs and digital ASICs in networking, communications, consumer, industrial and office automation equipment, including router and network cards, printers and LCD TVs.

Key features of SC286 include:
VIN: 2.9V to 5.5V; VOUT: pin-programmable 0.8V to 3.3V
World's smallest 4A dual POL regulator: 28-pad MLPQ package, 4 x 4 x 0.6mm
Works with very small chip inductors enabling an ultra-compact, <200mm2 solution footprint
Integrated VID pins to pin-select output voltages or for dynamic voltage scaling (DVS)
low shutdown current 1µA type
1.6MHz switching frequency
Efficiency up to 95%
Fast transient response

"The SC286 enables designers to source one device for multiple sockets. A total of 15 different output voltages from each of two on-chip regulators equates to 225 preset output voltage combinations controlled by one extremely small power management chip. This dramatically simplifies design, qualification and ongoing inventory management for our customers," said Alan Burchfield, Senior Product Marketing Manager for Semtech's Power Management Group. "It also helps them minimize overall system size even as they continue to add more and more functions. No other supplier comes close to matching two 4A regulators in such a small package."

Available: Now in production quantities
Price: $3.36 each for 3,000-piece lots
Package: 4 x 4 x 0.6mm MLPQ 28-pad package
