Single, quick-PWM step-down controller with dynamic REFIN in tiny TDFN package
(Product News, 15 Apr 2008 )
Maxim Integrated Products has introduced the MAX17024 single, Quick-PWM step-down controller with dynamic REFIN. This device utilizes Maxim's proprietary, constant-on-time, Quick-PWM architecture to support wide input/output voltage ratios and provide excellent transient response, while maintaining a relatively constant switching frequency. Operating from a 0 to 24V input voltage, the MAX17024 can generate any output voltage from 0 to Vin. Additionally, it increases flexibility by allowing the use of any kind of output capacitor; compensation is not required if using polymers or tantalum capacitors. Packaged in a tiny, 3mm x 3mm, 14-pin TDFN package, this controller is ideal for stepping down high voltages in notebook applications.
The MAX17024 features overvoltage, undervoltage, and thermal protection, and it is fully specified over the -40 degrees Celsius to +85 degrees Celsius extended industrial temperature range.
