Product Description

The XC9268 is a synchronous step-down DC/DC with P-Ch High Side Switch to ensure low voltage operation with 100% max duty ratio. It can operate from
3.0V~36.0V and deliver loads up to 600mA making it an ideal replacement for inefficient Linear Regulators used in many industrial applications.

Designed for very high efficiencies at low output loads, with low quiescent current and automatic PFM/PWM mode. The XC9268 also works with Low ESR ceramic capacitors and comes with a choice of two switching frequencies, adjustable soft start and a power good output.

Available in the ultra-small USP-6C package, measuring only 2.0 x 1.8 x 0.6mm an extremely small DC/DC circuit can be implemented with a minimal number of external components.

The XC9268 includes a fold-back type current limit circuit and the IC will automatically resume normal operation as soon as the over-current condition disappears.
