RP402Nxx
features the plete output disconnect shutdown option and the input-to-output bypass shutdown option. The RP402xxxx A/ B/ E/ F incorporates the plete output disconnect shutdown option, which allows the output to be disconnected from the input. The RP402xxxx C/ D/ G/ H incorporates the inputto-output bypass shutdown option, which allows the output to be connected to the input.
The RP402x is protected against damage by a short-current protection, an over-voltage lockout, an over voltage protection, an anti-ringing switch and a latch-type protection. An anti-ringing switch prevents the occurrence of noise when an inductor current reaches a discontinuous mode. The RP402x provides optional Latch function with current limit detection which can turn off the power in case the limit values are detected for a fixed time and current limit circuit controls peak inductor currents in every clock. The latch-type protection can be released by switching the CE pin from high to low while the power is...
