General Description
The RT8223P is a dual step-down, switch-mode power supply controller generating logic-supply voltages in battery-powered systems. It includes two Pulse Width Modulation (PWM) controllers adjustable from 2V to 5.5V, and also features fixed 5V/3.3V linear regulators. Each linear regulator provides up to 100mA output current with automatic linear regulator bootstrapping to the PWM
outputs. The RT8223P includes on-board power up sequencing, a power good output, internal soft-start, and soft-discharge output that prevents negative voltage during shutdown.
The constant on-time PWM scheme can operate without sense resistors and provide 100ns load transient response while maintaining nearly constant switching frequency. To eliminate noise in audio applications, an ultrasonic mode is included, which maintains the switching frequency
above 25kHz. Moreover, the diode-emulation mode maximizes efficiency for light load applications. The RT8223P is available in a WQFN-24L 4x4 package.
