30V Internal Switch LCD Bias Supply
General Description
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.
The MAX1605 uses a unique control scheme providing
the highest efficiency over a wide range of load condi-
tions. An internal 0.5A MOSFET reduces external com-
ponent 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 com-
ponent size in low-current applications.
Additional features include a low quiescent supply cur-
rent 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 applica-
tions. A MAX1605EVKIT evaluation kit (EV kit) is avail-
able to help speed up design time.
