ACOT® Buck Converter
Introducing our new cost-effective, high performance ACOT Buck
converters for Set Top Boxes, industrial and commercial low power
systems, computer peripherals and LCD Monitors and TVs.
ACOT Introduction
Richtek has introduced the whole range of ACOT Buck converters from
1.5A to 5A output
current capacity in HTSSOP-14,
DFN3x3, PSOP-8, and SOT23-6 packages. The input range
is from 4.5V to 18V
and the output is adjustable from
0.765V to 8V. The ACOT Buck converters
are ideal for Set Top Boxes,
industrial and commercial low power systems,
computer peripherals
and LCD Monitors and TVs.
ACOT Product Key Features
Constant Average Frequency:
Highly flexible and cost effective multi-rail power solution in
one chip ideal for high power density applications.
Ultra-Fast Transient Response:
"Instant On" response provides ultra-fast transient response.
Stable with MLCC:
ACOT supports MLCC operation with the lowest component count and
requires no external compensation or ripple injection scheme.
ACOT
Advantages
The proprietary ACOT control scheme not only features
ultra-fast transient response
but also improves upon legacy constant on-time architectures, achieving
constant average frequency
over line, load and output ranges to minimize interference and noise
problems. The ACOT Buck converters are stable with and optimized for
ceramic output capacitors
without external components or external ripple injection scheme. The
ACOT family includes latch-off,
hiccup and constant current protection modes.
The ACOT family is the latest addition to Richtek's comprehensive Buck
converter products, providing full functionality and a cost-effective
solution.
