CX8508 - Monolithic synchronous buck regulator

Datasheet Summary

Description

The CX8508 is a monolithic synchronous buck regulator.

The device integrates 100mΩ MOSFETS that provide 2A continuous load current over a wide operating input voltage of 4.75V to 25V.

Current mode control provides fast transient response and cycle-by-cycle current limit.

DESCRIPTION The CX8508 is a monolithic synchronous buck regulator. The device integrates 100mΩ MOSFETS that provide 2A continuous load current over a wide operating input voltage of 4.75V to 25V. 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 1 μA. This device, available in an 8-pin SOIC package, provides a very compact system solution with minimal reliance on external components. FEATURES z 2A Output Current z Wide 4.75V to 25V Operating Input Range z Integrated 100mΩ Power MOSFET Switches z Output Adjustable from 0.
