S-8580/1 Series Synchronous Step-Down Switching Regulators
ABLIC's S-8580/1 series contributes to the downsizing of 12 V/24 V industrial equipment/home facilities
ABLIC's S-8580 and S-8581 series, 36 V (absolute maximum ratings 45 V) input and synchronous rectification switching regulators (DC-DC converters) adopt the ultra-small package HSNT-6 (2.46 mm x 1.96 mm). Suitable for industrial equipment, house facilities, and house appliances, the S-8580 and S-8581 contribute to downsizing machines or modules. The gull-wing type package, HTMSOP-8, is recommended when mountability is required.
Slope and phase compensation circuits in the S-8580 and S-8581 series have been optimized to provide a high transient response. The external high-output capacitors used to compensate for overshoot and undershoot have been downsized, contributing to lower costs.
