MAX1573ETE+T is a high-current,voltage-mode charge-pump dc-dc converter IC typically used for driving multiple light emitting diodes (LEDs) applications such as automotive,motorcycle, and consumer. This integrated circuit is ideal for driving programs such as flashing, brightness control, and logo illumination. The MAX1573ETE+T features a charge pump topology optimized for driving LEDs. It requires only two tiny ceramic external capacitors, minimizing component count to obtain high efficiency and reduce component costs. And it is well-suited to boost input voltages of 2V to 6V and can step up the output voltage to as high as 28V.

The MAX1573ETE+T is a high-current, voltage-mode charge pump dc-dc converter ic, designed to drive multiple LEDs with a wide range of operating voltages. The operating frequency can be set independently to provide a maximum step-up ratio of 16. The charge-pump circuit is very efficient because it operates in a discontinuous mode, utilizing only two external ceramic capacitors for compensation. The low component count and high efficiency make it ideal for automotive, motorcycle, and consumer applications.

The MAX1573ETE+T comes with several current control options, including an internal current sense amplifier and I2C input to program the operating current. The current sensing is done on the high-side to eliminate the need for a negative voltage source. The MAX1573ETE+T can control a string of alternating LEDs with one integrated circuit. And the LED current can be varied in steps to achieve flicker, brightness control, and logo illumination.

The working principle of MAX1573ETE+T is based on the charge pump voltage multiplier circuit. This circuitry converts an input voltage of 2V to 6V to output voltage of up to 28V and features a wide input voltage range. The charge-pump dc-dc converter ic utilizes two capacitive stages to boost the input voltage. The first stage is the charge pump, which charges an external capacitor to a higher voltage. Then, an output stage is used to step up the output voltage and deliver current to the string of LEDs.

The MAX1573ETE+T offers several protection features such as over-temperature, over-voltage, and over-current protection. Additionally, the IC has an internal under-voltage lockout that disables the output when the battery voltage drops below a certain level. The MAX1573ETE+T includes a wide range of current control options, including an internal current sense amplifier. This current sense amplifier senses the current supplied to the LEDs and dynamically adjusts it to ensure that the LED current remains constant.

In conclusion, the MAX1573ETE+T is an ideal choice for high-current LED driving applications such as automotive, motorcycle, and consumer applications. The integrated circuit offers high efficiency and low component count, and provides multiple current control options to achieve flicker, brightness control, and logo flashing. The use of a charge pump voltage multiplier circuit ensures that the output voltage can be stepped up to as high as 28V, making it ideal for driving programs.
