Sunnyvale, Calif.Maxim Integrated Products has introduced the MAX16816, a high-voltage, programmable, high-brightness (HB) LED driver for automotive and general lighting applications.
The MAX16816 provides many user-programmable features through on-chip nonvolatile EEPROM registers. Using a microcontroller and a single-wire interface, the programming is done either at the factory or by the designer in the field.
The MAX16816 integrates all the building blocks necessary to implement fixed-frequency HBLED drivers with wide-range dimming control. It is configurable to operate as a step-down (buck), step-up (boost) or step-up/down (buck-boost) current regulator. The device also includes an integrated, differential current-sense amplifier and a floating dimming driver that is capable of driving an n-channel MOSFET.
The MAX16816's programmable features include: soft-start, LED current adjust, external MOSFET gate-driver supply voltage, slope compensation, blanking time, and enabling/disabling of the internal PWM oscillator. This high level of programmability ensures the design flexibility needed for efficiency, size, and minimal EMI.
Pricing: Starts at $2.33 (1000-up, FOB USA).
