Description
The RC5037 is a high power, switch-mode DC-DC controller
that provides efficient power for all low-voltage applications.
This controller has a built-in Soft Start feature which offers
system protection during power-up by reducing both inrush
current and output overshoot. When combined with the
appropriate external circuitry, the RC5037 can deliver load
currents as high as 13A at efficiencies as high as 88%. The
RC5037 can generate output voltages from 1.5V up to 3.6V
using external resistors.
The RC5037 is designed to operate in a constant on-time
control mode under all load conditions. Its accurate low TC
reference eliminates the need for precision external compo-
nents in order to achieve the tight tolerance voltage regula-
tion required by many applications. Short circuit current
protection is provided through the use of a current sense
resistor, while overvoltage protection is provided internally.
