The MAX17582GTM+ is a low-voltage, low-cost synchronous buck voltage regulator specifically designed to power LED loads. It\'s a specialized type of switch-mode power supply with a wide range of applications, from USB charging to providing power for digital point-of-load systems. It can adjust output voltage to match a wide range of LED voltages. The MAX17582GTM+ has a step-up feature that can boost output voltage from 3V to 16V, based on the range of inputs from 2.3V to 16V.

The MAX17582GTM+ is ideal for applications that require high efficiency and accurate current regulation, such as backlighting for portable devices, consumer electronics, automotive displays, and digital signage. It works by switching inductor current on and off in discrete steps, diode rectification, and capacitor filtering steps to achieve a regulated output voltage.

The MAX17582GTM+ provides high-precision, constant-current output accuracy of ±3%, low output ripple, fast transient response, and up to 98% efficiency. It also offers a wide range of features, including short-circuit protection and thermal shutdown. The device also features a power-saving sleep mode and adjustable voltage soft-start. It is available in a 16-pin, 4x4mm TQFN package, and is compatible with 1.5mm-high micro-BGA packages.

The MAX17582GTM+ has a typical start-up time of ≤200us and a fixed switching frequency of 200kHz. It consists of an integrated step-down voltage regulator and an output transistor with adjustable peak current. The voltage regulator is controlled using pulse-width modulation (PWM) with a programmable overcurrent protection level. The output transistor provides a constant peak current to the LED by controlling the duty cycle of the PWM. The peak current level is set using an external resistor, and the device also provides a peak current-sense feedback which can be used to detect and react to overcurrent faults.
