RT8206B - Main Power Supply Controller

Download the RT8206B datasheet PDF. This datasheet also covers the RT8206A variant, as both devices belong to the same main power supply controller family and are provided as variant models within a single manufacturer datasheet.

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.

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. A constant on-time PWM control scheme operates without sense resistors and provides 100ns response to load transients while maintaining a relatively const.

RT8206A/B High Efficiency, Main Power Supply Controllers for Notebook Computers 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.
