The RT8203 dual step-down, Switch Mode Power Supply (SMPS) controllers generate logic-supply voltages in battery-powered systems. The RT8203 include two pulse-width modulation (PWM) controllers, adjustable from 2V to 5.5V or fixed at 5V and 3.3V. These devices feature two linear regulators providing 5V and 3.3V always-on outputs.

Purpose
● The HTOL test is to demonstrate the quality or
   reliability of device subjects to the
   specified conditions over an extended time period.
● The ESD tests are used to classify the
   electrostatic discharge of microcircuits.
● The latch-up test is used to check IC latch-up characteristics.
● The environment tests are to ensure the process
   of assembly of this package type that
   meets Richtek quality specifications.
