ACOT™ Buck Converter
Richtek has introduced a wide range of ACOT Buck converters from 1.5A to 5A output current capacity in HTSSOP-14, DFN3x3, PSOP-8, and SOT23-6 packages. They support an input range from 4.5V to 18V and the output is adjustable from 0.765V to 8V.
ACOT Buck converters are ideal for Set Top Boxes, industrial and commercial low power systems, computer peripherals and LCD Monitors and TVs.
Constant Average Frequency:
The frequency locked loop control provides constant average frequency over line and load.
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.
