36V 0.6A Synchronous Step-Down DC/DC Converter
The XD9268 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. Designed for very high efficiencies at low output loads,with low quiescent current and automatic PFM/PWM mode.
The XD9268 works with Low ESR ceramic capacitors and utilises a 2.2MHz switching frequency so a smaller Inductor can be used, It also includes adjustable soft start for sequencing 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 XD9268 includes a fold-back type current limit circuit and the IC will automatically resume normal operation as soon as the over-current condition disappears.
