LSP5502
manufacturer
Lite-On
2A Synchronous Step Down DC/DC Converter
The LSP5502 is a monolithic synchronous buck regulator. The device integrates 120mΩ MOSFETS that provide 2A continuous load current over a wide operating input voltage of 4.5V to 27V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn on. In shutdown mode, the supply current drops below 1µA. This device, available in an 8-pin SOP package, provides a very compact system solution with minimal reliance on external components.
