The XC9267/68 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 3.0 V~36.0 V and deliver loads up to 600 mA making it an ideal replacement for inefficient Linear Regulators used in many industrial applications.
Available in the ultra-small USP-6C package, measuring only 2.0 × 1.8 × 0.6 mm an extremely small DC/DC circuit can be implemented with a minimal number of external components.
Designed for very high efficiencies at low output loads, with low quiescent current and automatic PFM/PWM mode. The XC9267/68 also works with Low ESR ceramic capacitors and comes with a choice of two switching frequencies, adjustable soft start and a power good output.
