NEO-ISO ISOLATED LOAD SWITCHES
™
Semtech Neo-Iso™ technology enhances Internet of Things applications by adding higher levels of intelligence and control. Neo-Iso
switches make it possible for low-power microcontrollers to control
high voltage loads in the system. Reporting of fault conditions from
the switch to the controller enables system responses resulting in
safer, more efficient operation. Low current draw allows each switch
to operate off of power harvested from the load, eliminating the
need for additional supplies.
BOOST CONVERTERS
Semtech’s expanded line of boost converters now includes the
world’s smallest low-voltage regulators, as well as a growing line of
single- and multi-string boost LED drivers for demanding, rugged
backlighting applications.
LDOS
A wide range of ultra-low dropout regulators offers ideal solutions
for systems where VOUT is very close to VIN.
LED DRIVERS
Semtech manufactures an extensive line of LED driver ICs for LCD
display, automotive, backlight and LED camera flash applications.
They include inductor-based boost LED drivers for series-connected
LEDs and charge pump LED drivers and low-dropout current sinks
for parallel-connected LEDs. Each LED Driver topology is designed
for optimal high efficiency in the smallest footprint with accurate
current regulation, low noise, and a wide dimming range.
BUCK CONVERTERS
LOAD SWITCHES
With one of the industry’s broadest selections of buck converters,
Semtech also offers some of the world’s smallest, high-performance
point-of-load (POL) regulators. These include our family of
EcoSpeed® converters that set a new standard for efficiency, speed,
size and simplicity in emerging green energy applications.
Semtech’s new Load Switch products focus on Lowest RDS ON in
class for highest system efficiency, and extremely robust protection
to withstand the harshest circuit conditions.

EcoSpeed® Regulators
EcoSpeed® converters provide high efficiency across the entire load range with a power save (PSAVE) feature that lowers the switching
frequency to cater to low-power standby requirements. This reduces power FET switching losses and results in greater than 90% peak standby
efficiency during light loads. When the load changes from standby to steady state, the EcoSpeed converter’s cycle-by-cycle response quickly
exits PSAVE mode providing very fast wake-up recovery time. All EcoSpeed converters offer SmartDrive™, a two-step, high-side FET turn-on
scheme that reduces EMI.

20MHz Buck Regulator
The SC220/Q is a 20MHz X-EMI™enabled step-down regulator optimized for power low voltage rails from 2.7 to 5.5V input voltage. X-EMI™
inductor technology enables inductors to be drawn directly on the PC board. This technology meets or exceeds the EMI performance of chip
inductors and eliminates the need for discrete inductors.
BENEFITS
• 20MHz PWM operation
• High efficiency
VIN = 2.7V to 5.5V
SW
• Ultra-fast transient response
220nH
VOUT = 1V to 0.9VIN
IOUT = 650mA
PVIN
• 650mA output current
AVIN
• 19µA quiescent current
OUT
SC220
• 0.1μA shutdown current
• Automatic Power Save mode
FB
• EN/SYNC frequency sync function
Enable
• SOIC-8 package
VFB = 1V
