Switching at 500 kHz, the converter uses a small inductor and ceramic output capacitor — the inductor ripple current stays manageable without pushing core losses into the thermal budget. ## Input range and dimming flexibility Dimming is supported in both analog and PWM modes — analog sets the LED current level continuously, while PWM dimming controls brightness by duty cycle, avoiding colour shift at low currents.","metaTitle":"BD9422EFV-E2 ROHM LED Driver, Boost, 6-Ch, 400mA, 40-HTSSOP","metaDescription":"ROHM BD9422EFV-E2 DC-DC boost LED driver, 6 outputs at 400mA each, analog/PWM dimming, 500kHz switching, 9-35V input.
