The MAX17761ATC+T is a versatile three-channel DC/DC switching regulator IC from Texas Instruments that is well suited for applications in the field of power management, such as LEDs and specialty applications. The device enables three independent channels of synchronized DC/DC regulation, with each channel capable of delivering up to 30 A of continuous current. This multichannel device can be used as a single device for multiple dedicated power distributions, or for simultaneous charge and discharge power supplies.

The MAX17761ATC+T has six fixed output voltage options: 3.3, 5, 12, 15, 24, and 48 V. The device is externally configurable using a single resistor to control the output voltage. It also features comprehensive power save mode, short-circuit protected sensing, adjustable current limitation and over voltage protection. The device excels at handling fast transient currents due to its large switch capacitance.

The MAX17761ATC+T employs typical buck-type switching converters architecture that utilizes two switches for power conversion. On the output side, an inductor current is used to produce a continuous output voltage and an improved load-transient response. On the input side, a reference voltage is compared to the input voltage, and a voltage error is used to drive the gate of an internal MOSFET switch.

The working of the MAX17761ATC+T consists of five main stages: Soft Start, Control Loop, PWM Signal, On-Time Calculation and Output Control. The first stage, Soft Start, connects an internal charging capacitor with the output node once power source is connected to the device. The second stage, Control Loop, compares the feedback voltage to the reference voltage. If the two are not equal, the duty cycle resets and the loop continually adjusts until the criteria is met. In the third stage, PWM signal, a signal is generated from the duty cycle values of each output. On-Time Calculation, in the fourth stage, happens when the Duty Cycle exceeds the timer period and in the fifth stage, Output Control, the power MOSFET switch is turned ON and OFF.

The MAX17761ATC+T is an advanced, high performance, three-channel DC/DC switching regulator IC that can be used to efficiently power LED applications, providing up to 30 A of continuous current per channel. Due to its high efficiency and low quiescent current, it is suitable for any low power system application. Its features save time and cost, while making it easy to integrate in any design environment.
