Technical Details & Description

Device function and key parametrics

The BD9470AFM-GE2 from ROHM Semiconductor is a DC DC regulator LED driver using a Step-Up (Boost) topology, designed for backlight applications. It integrates six output channels, each capable of delivering up to 250 mA, with PWM dimming control. The switching frequency is fixed at 150 kHz, and the device includes internal switches, simplifying the external component count. The supply voltage range spans 9 V to 35 V, accommodating common automotive and industrial backlight rails. Operating temperature covers -40°C to 85°C, suitable for ambient environments without active cooling. The 28-SOP package with 2 heat tabs (28-HSOP-M) provides a thermal path for the power dissipated across the six channels at full load.
