RT8223MZQW Descrizione generale

General DescriptionThe RT8223L/M 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 RT8223L/M includes on-board power up sequencing, a power good output, internal soft-start, and soft-discharge output that prevents negative voltage during shutdown.Features● Constant On-time Control with 100ns Load Step Response● Wide Input Voltage Range : 6V to 25V● Dual Adjustable Outputs from 2V to 5.5V● Fixed 3.3V and 5V LDO Output : 100mA● 2V Reference Voltage● Frequency Selectable via TONSEL Setting● 4700ppm/°C RDS(ON) Current Sensing● Programmable Current Limit Combined with Enable Control● Selectable PWM, DEM, or Ultrasonic Mode● Internal Soft-Start and Soft-Discharge● High Efficiency up to 97%● 5mW Quiescent Power Dissipation● Thermal Shutdown● RoHS Compliant and Halogen FreeApplications● Notebook and Sub-Notebook Computers● 3-Cell and 4-Cell Li+ Battery-Powered Devices
