Power ICs

By Staff Author | January 21, 2004

The XC9508/09 series is a family of synchronous rectification type DC/DC converters with built in high speed, low noise LDO voltage regulator and an internal comparator for low voltage detection, all in a chip scale USP-10 (2.7 &#215 2.6 &#215 0.6 mm) package. The XC9508/09 is a suited partner for DSPs and microcontrollers which require 1.8 V for the memory (taken from the DC/DC portion of the IC) and 1.5 V for the core (provided by the LDO portion of the IC). The device’s 0.6 Ω P-channel driver transistor and 0.6 Ω N-channel switching transistor means that efficiencies over 90% can be achieved without an external Schottky diode. The XC9508/09 is designed for use with low ESR ceramic capacitors and small chip inductors. Output current is 600 mA (DC/DC converter), 200 mA (voltage regulator). Operating voltage range is 2.4 to 6.0V. Three switching frequencies are available: 300 kHz, 600 kHz or 1.2 MHz. Other features include a built-in current limit, an internal soft-start (set to 10 ms) and an under voltage lock-out circuit.
