• 2.5A Internal Switch • Operating Input Voltage from 4.7V to 22V • 3.3V ±2% Reference Voltage • Output Voltage: APW1172 - adjustable from 1.235V to 20V • Low Dropout Operation: 100% Duty Cycle • 250kHz Internally Fixed Frequency • Voltage Feed-Forward • Zero Load Current Operation • Internal Current-Limit • Inhibit for Zero Current Consumption • Synchronization • Protection against Feedback Disconnection • Thermal Protection • External Soft-Start • Over-Voltage Protection • Lead Free and Green Devices Available (RoHS pliant) Applications • Consumer: STB, DVD, TV, VCR, Car Radio, LCD monitors • Networking: XDSL, Modems, DC-DC Modules • puter: Printers, Audio/Graphic Cards, Optical Storage, Hard Disk Drive • Industrial: Chargers, Car Battery DC-DC Converters The APW1172 is a step down monolithic power switching regulator with a switch current limit of 3.8A so it is able to deliver more than 2.5A DC current to the load depending on the application conditions.
The output voltage can be set from 1.235V to 22V.The high current level is also achieved thanks to an SOP8 package with exposed pad frame.
The type of package allows to reduce the Rth (j-amb) down to approximately 45°C/W.
