MAX1837EUT50+T
MAX1837EUT50+T - Brand New Maxim Integrated DC Switching Regulators
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
General Description
The MAX1836/MAX1837 high-efficiency step-down converters provide a preset 3.3V
or 5V output voltage from supply voltages as high as 24V. Using external
feedback resistors, the output voltage can be adjusted from 1.25V to VIN. An
internal current-limited switching MOSFET delivers load currents up to 125mA
(MAX1836) or 250mA (MAX1837).
The unique current-limited control scheme, operating with duty cycles up to
100%, minimizes the dropout voltage (120mV at 100mA). Additionally, this
control scheme reduces supply current under light loads to 12μA. High
switching frequencies allow the use of tiny surface-mount inductors and output
capacitors.
The MAX1836/MAX1837 step-down converters with internal switching MOSFETs are
available in 6-pin SOT23 and 3mm x 3mm TDFN packages, making them ideal for
low-cost, low-power, space-sensitive applications. For increased output drive
capability, use the MAX1776 step-down converter that uses an internal 24V
switch to deliver up to 500mA. For even higher currents, use the
MAX1626/MAX1627 step-down controllers that drive an external P-channel MOSFET
to deliver up to 20W.
