| Manufacturer | Richtek |
| Description | The RT8249D is a dual-channel step-down, controller generating supply voltages for battery-powered systems. It includes two Pulse-Width Modulation (PWM) controllers adjustable from 2V to 5.5V, and two... |
| Features |
include on-board power-up sequencing, a power-good output, internal soft-start, and soft-discharge output that prevents negative voltage during shutdown.
A constant current ripple PWM control scheme operates without sense resistors and provides 100ns response to load transient. For maximizing power efficiency, the RT8249D automatically switches to the diode-emulation mode in light load applications. The RT8249D is available in the WQFN-20L 3x3 package.
Features
Support Connected Standby Mode for Ultrabook CCRCOT Control with 100ns Load Step Response PWM Maximum Duty Ratio > 98% 5V to ... |
