Richtek RT 8206A IC Regulator QFN-32Brand new Richtek RT8206A QFN 32 General Description The RT8206A B dual step down, Switch Mode Power Supply (SMPS) controller generates logic supply voltages in battery powered systems. The RT8206A B includes two Pulse Width Modulation (PWM) controllers fixed at 5V 3. 3V or adjustable from 2V to 5. 5V. An optional external charge pump can be monitored through SECFB (RT8206A). This device also features a linear regulator providing a fixed 5V output.

Brand new Richtek RT8206A QFN-32

General Description

The RT8206A/B dual step-down, Switch Mode Power Supply (SMPS) controller generates logic supply voltages in battery powered systems. The RT8206A/B includes two Pulse Width Modulation (PWM) controllers fixed at 5V/3.3V or adjustable from 2V to 5.5V. An optional external charge pump can be monitored through SECFB (RT8206A). This device also features a linear regulator providing a fixed 5V output. The linear regulator provides up to 70mA output current with automatic linear regulator bootstrapping to the BYP input. The RT8206A/B includes on-board power up sequencing, the power good outputs, internal soft-start, and internal soft-discharge output that prevents negative voltages on shutdown.
