Automotive charge-pump regulator with SPI dimming
The Infineon BTS5562EAUMA1 is a DC DC regulator using a switched capacitor (charge pump) topology, designed for automotive applications that require multiple regulated outputs with digital dimming control via SPI. It integrates five outputs, each capable of delivering 24 A, with internal switches, and operates over a supply range of 5.5 V to 28 V.
SPI dimming and multi-channel current capability
The SPI dimming interface allows individual control of each of the five output channels, enabling dynamic brightness adjustment or sequencing in automotive lighting systems such as matrix headlamps or interior ambient lighting. Each channel is rated for 24 A continuous output current, which is unusually high for a multi-channel charge-pump regulator — this part is built for high-power loads, not low-current signal paths.
Lifecycle status — obsolete, sourced on request
The BTS5562EAUMA1 carries an Obsolete product status per the manufacturer, meaning Infineon has ended production and no further factory orders are accepted.
