Torex XD9707/08

The XD9707/XD9708 series has an operating voltage range of 3V to 36V, a switching frequency of 2.2MHz, and the circuit scheme of synchronous rectification to be a highly efficient and stable power supply. An internal reference voltage source of 0.75V is available, and the output voltage can be set to 1.8V to 12V by external resistor.

Designed for very high efficiencies at low output loads with low quiescent current and automatic PFM/PWM mode.

The XD9707/08 includes a fold-back type current limit circuit and the IC will automatically resume normal operation as soon as the over-current condition disappears.

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.
