TPS65257 Product details

Description

ORDERING INFORMATION TPS65257 is a power management IC with three step-down buck converters.Both high-side and low-side MOSFETs are integrated to provide fully synchronous conversion with higher efficiency.The converters are designed to simplify its application while giving the designer the option to optimize their usage according to the target application.The converters can operate in 5-, 9-, 12- or 15-V systems.The output voltage can be set externally using a resistor divider to any value
