600mA Synchronous HiSAT-COT Step-Down DC/DC Converter
Available in a tiny WLP-5-08 chip scale package, measuring just 0.88mm x 0.96mm x 0.33mm (max), the XC9290 series is one of the smallest DC/DC currently available from Torex. The WLP-5-08 has 5 solder bumps, each with a 0.25mm diameter, placed on a 0.5mm pin-pitch. The bump size and configuration is fully compatible with similar products available from other vendors.
HiSAT-COT control ensures ultra-fast load transient response performance whilst maintaining a stable switching frequency.
The XC9290 provide a high efficiency (Typ 90%) and a stable power supply with output currents of up to 600mA achievable using only a coil and two ceramic capacitors connected externally.
Minimum operating voltage is 2.5V and output voltage is fixed within a range of 0.7V to 3.6V in 50mV steps (accuracy: ± 2.0%). Switching frequency is selectable from either 4MHz or 6MHz.
During standby, all circuits are shutdown to reduce current consumption.
