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."
