MAX1605

30V Internal Switch LCD Bias Supply

General Description

Features

The MAX1605 boost converter contains a 0.5A internal

switch in a tiny 6-pin SOT23 package. The IC operates

from a +2.4V to +5.5V supply voltage, but can boost

battery voltages as low as 0.8V up to 30V at the output.

● Adjustable Output Voltage up to 30V

● 20mA at 20V from a Single Li+ Battery

● 88% Efficiency

● Up to 500kHz Switching Frequency

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 to 500mA, 250mA, or 125mA, allowing

the user to reduce the output ripple and component size

in low-current applications.

● Selectable Inductor Current Limit

(125mA, 250mA, or 500mA)

● 18μA Operating Supply Current

● 0.1μA Shutdown Current

● Available in Two Small Packages

• 6-Pin TDFN

• 6-Pin SOT23

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.
