an ambient temperature range of -40 to +125°C, the ELMOS ICs are made especially for use in harsh environments such as automotive conditions or exterior lighting. Other fields of use are interior house lights and TFT backlighting.
In addition to high robustness, the components offer a great variety in the selection of circuit topologies, such as boost, SEPIC, buck-boost, and buck. The switching frequency can be adjusted to up to 600kHz by means of an external resistor or synchronized with other components in master-slave configuration. Power consumption in sleep mode is only 8µA.
The versatility of the E522.3x controller family is completed by various control and monitoring functions, e.g. protection against short-circuit, overtemperature, overvoltage and undervoltage, and load break.
This IC family is supplied in the shape of single or dual controller in a QFN32L5 package.
