DESCRIPTION
Capable of driving a 0.5A load over a 9V-42V input voltage range, this device is easy to apply and is provided in the small VSSOP-8 and the thermally enhanced WSON-8 packages. Ultra-fast transient response is achieved through the use of a constant on-time architecture with Vin feed forward. This architecture is easy to use and tolerant of component selection.
