Description
MAX1605EUT-T Maxim Integrated LCD Drivers 30V Internal Switch LCD Bias Supply
The MAX1605 boost converter contains a 0.5A internal switch in a tiny 6-pin SOT23 package. The IC operates from to +5.5V supply voltage but can boost battery voltages as low 28V at the output. The MAX1605 uses a unique control scheme providing the highest efficiency over a wide range of load conditions. An internal 0.5A MOSFET reduces external component count, and a high switching frequency (up to 500kHz) allows for tiny surface-mount components. The current limit can be set or 125mA, allowing the user to reduce the output ripple and component size in low-current applications. Additional features include a low quiescent supply current and a shutdown mode to save power. The MAX1605 is ideal for small LCD panels with low current requirements but can also be used in other applications. A MAX1605EVKIT evaluation kit (EV kit) is available to help speed up design time. o Adjustable Output Voltage at 20V from a Single Li+ Battery o 88% Efficiency to 500kHz Switching Frequency o Selectable Inductor Current Limit o 18µA Operating Supply Current o 0.1µA Shutdown Current o Small 6-Pin SOT23 Package.
