产品概述
The LM26484 is a multi-function, configurable Power Management Unit. This device
integrates two highly efficient 2.0A Step-Down DC/DC converters, one LDO Controller, a POR (Power
On Reset) circuit, and thermal overload protection circuitry. All regulator output voltages are
externally adjustable. The LDO controller is a low-voltage NMOS voltage regulator. The LM26484 is
offered in a 5 x 4 x 0.8 mm WQFN-24 pin package.
