Richtek EVB_RT4531WSC

20毫安31V2.5V~5.5V

Overview

The RT4531WSC is a dual-channel current source with high-efficiency asynchronous boost converter for backlight application. The RT4531WSC has built-in 1.5A/36V power MOSFET and two high current-matching capability current sink, so RT4531WSC can drives up 10s2p white LED. The RT4531WSC can allow very low voltage headroom control, therefore to improve LED strings efficiency effectively. The RT4531WSC supports both PWM dimming and 1-wire digital dimming interface and it can realize 10 bit brightness code programming. The RT4531WSC provides complete protection functions such as input Under-Voltage Lockout (UVLO), Over-Current Protection (OCP), Output Over Voltage (OVP) and Over-Temperature Protection (OTP). The RT4531WSC is available in the WL-CSP-9B 1.35x1.35 (BSC) package.
