XC9213 - Synchronous Step-Down DC/DC Controller

Description

The XC9213 series is N-ch & N-ch drive, synchronous, step-down DC/DC controller IC with a built-in bootstrap driver circuit.

Output will be stable no matter which load capacitors, including low ESR capacitors, are used.

Resistance (RSENSE) of about several 10mΩ will be required as a current sense.

XC9213 Series ETR05005-005 Synchronous Step-Down DC/DC Controller IC - Input Voltage : 25V ☆Green Operation Compatible ■GENERAL DESCRIPTION The XC9213 series is N-ch & N-ch drive, synchronous, step-down DC/DC controller IC with a built-in bootstrap driver circuit. Output will be stable no matter which load capacitors, including low ESR capacitors, are used. Resistance (RSENSE) of about several 10mΩ will be required as a current sense. The phase compensation is also run when a low ESR capacitor is used. In addition, the circuit is double protected by the ways of limiting the current while detecting overshoot current and making output shutdown at any given timing by a protection time setting capacitor (CPRO). The output voltage can be set freely within a range of 1.5V~15.0V with 1.
