MAX20053AUD/V+G2Z

PMIC - LED Drivers

MAX20053AUD/V+G2Z is a constant current 2-channel LED driver based on MAX20053 and designed for multiple lighting applications. With ultra-low quiescent current, wide input voltage range and flexible I2C dimming, the device is well-suited for battery powered devices, such as mobile phones and tablet devices.

Application Field

The MAX20053AUD/V+G2Z is suitable for multiple LED lightings applications, such as monitor displays, automotive interior lightings and backlighting for buttons. Moreover, with integrated I2C dimming and wide input voltage range, it also works for low power input such as battery-powered applications, including mobile phones, PDAs and tablet devices. Integrating two channels for LED controlling, MAX20053AUD/V+G2Z permits to provide individual control for each LED source.

Working Principle

MAX20053AUD/V+G2Z integrates a maximum of two strings of 16 LEDs each. Each output is powered through a regulated current size that can be configured through I2C control. Outputs are disabled when string is not connected to the light source. It operates with a wide input voltage of 4.25V to 20V and provides up to 18V output voltage. Short-circuit and thermodinamic protection are integrated for protection of the device. Furthermore, MAX20053AUD/V+G2Z integrates a hysteresis start-up, an I2C dimming capability and intelligent and stable PWM dimming.

Widgets Control and Protection

MAX20053AUD/V+G2Z offers integrated I2C dimming for brightness control over two power delivery channels. User can individually control each LED output current. This device compensates brightness variation of LEDs due to changes in temperature. It supports up to 18V LED maximum DC voltage and provides overcurrent and thermal protection.

Conclusion

MAX20053AUD/V+G2Z is an ideal LED driver for multiple lighting applications, targeting specificly battery powered systems such as mobiles and tablets. It offers a smart I2C Dimming system, high output voltage support up to 18V, efficient and stable PWM demming and integrated short-circuit and thermal shutdown protection. Therefore, MAX20053AUD/V+G2Z is an optimal LED driver for multiple LED lighting applications.
