MAX618EEE+

The MAX618EEE+ is designed as one kind of 28V, PWM, step-up DC-DC converter that can be used in palmtop computers, LCD displays, industrial +24V and +28V systems and automotive-powered DC-DC converters. Also this device is available in a thermally enhanced 16-pin QSOP package that is the same size as an industrystandard 8-pin SO but dissipates up to 1W. An evaluation kit (MAX618EVKIT) is available to help speed designs.

Features of the MAX618EEE+ are:(1)adjustable output voltage up to +28V; (2)up to 93% efficiency; (3)wide input voltage range (+3V to +28V); (4)up to 500mA output current at +12V; (5)500A quiescent supply current; (6)3A shutdown current; (7)250kHz switching frequency; (8)small 1W, 16-pin QSOP package.

The absolute maximum ratings of the MAX618EEE+ can be summarized as:(1)IN to GND:-0.3V to +30V;(2)LX to GND:-0.3V to +30V;(3)VL to GND:-0.3V to +6V;(4)SHDN, COMP, FB to GND:-0.3V to (VL + 0.3V);(5)PGND to GND:±0.3V;(6)continuous power dissipation (TA=+70°C) 16-pin QSOP (derate 15mW/°C above +70°C):1 W;(7)operating temperature range:-40°C to +85°C;(8)junction temperature:+150°C;(9)storage temperature range:-65°C to +150°C;(10)soldering temperature (reflow):+260°C.
