Controller IC Chip - Richtek RT8243AZQW, RT8243A QFN-20 chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0155)
The RT8243A/B/C is a dual step down, Switch Mode Power Supply (SMPS) controller which generates logic supply voltages for battery powered systems. It includes two Pulse Width Modulation (PWM) controllers adjustable
from 2V to 5.5V and also two fixed 5V/3.3V linear regulators. One of the controllers (LDO5) provides automatic switch over to the BYP1 input connected to the main SMPS1 output for maximized efficiency. An optional external charge pump can be monitored through SECFB (RT8243B/C). Other features include on board power up sequencing, a power good output, internal softstart, and a soft discharge output that prevents negative voltage during shutdown.
