Foto datasheet rt8206 a atau B
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.A constant on-time PWM control scheme operates without
sense resistors and provides 100ns response to load transients while maintaining a relatively constant switching frequency. The unique ultrasonic mode maintains the switching frequency above 25kHz, which eliminates noise in audio applications. Other features include Diode Emulation Mode (DEM), which maximizes efficiency in light load applications, and fixed frequency PWM mode,
which reduces RF interference in sensitive application. The RT8206A/B is available in the WQFN-32L 5x5 package.
