Introduction
The MAX16520GFB+ is a Dual/Quad-Output, High-Efficiency, High-Voltage, DC/DC Step-Down Switching Controller PMIC from Maxim Integrated. The device features adjustable output voltage up to 32V, digital control and a wide range of external features. The MAX16520GFB+ is part of Maxim\'s MAXimium-Efficiency solutions and is designed to deliver a range of features making it suitable for automotive, industrial, medical and consumer applications.
Device Features
The MAX16520GFB+ is a high-efficiency, high-voltage DC/DC pressure-mode step-down switching controller with two or four channels of independent output voltage control and a built-in pulse-skipping mode. It can support up to 500 kHz switching or boost frequency and up to 600 kHz, programmable switching frequency.
Its output voltage is adjustable up to 32V with ±2% accuracy, and it has current-limit protection overvoltage, undervoltage and over-temperature protection, high speed short circuit protection and frequency synchronizing (optional). It also offers diagnostic functions such as rising and falling edge lockout, duty cycle range detection and programmable soft-start.
Other features include an internal amplifier with gain of up to 31 for improving load transient performance and a power-saving mode reducing current consumption down to 10µA.
Typical Applications
The MAX16520GFB+ is suited for a range of applications including:
- Automotive ambient lighting.
- Automotive point-of-load supplies.
- Industrial automation.
- Medical products.
- Consumer electronics.
Working Principle
The MAX16520GFB+ is a dual/quad-output, high-efficiency, high-voltage, DC/DC switching controller with adjustable output voltage up to 32V. It is designed to provide the highest possible efficiency by converting the input voltage to a regulated output voltage with minimum energy losses.
The device uses a pulse-width modulation (PWM) control scheme for maintaining a nearly constant output voltage, regardless of changes in input voltage and load current. The device generates a pulse-width modulated (PWM) signal with a fixed switching frequency, allowing the user to set the required output voltage.
At each cycle, the device’s feedback control loop monitors the output voltage, comparing it to the set point and adjusting the duty cycle (the percentage of time on compared to time off) of the PWM signal accordingly. A higher duty cycle means more time on and more current supplied to the load, causing the output voltage to rise, while a lower duty cycle leads to less current and a lower output voltage.
Conclusion
The MAX16520GFB+ is an advanced dual/quad-output, high-efficiency, high-voltage, DC/DC switching controller designed for a range of applications such as automotive, industrial, medical and consumer electronics. It features adjustable output voltage up to 32V, digital control, current-limit protection, and a range of external features for improved power management and system performance. It uses a pulse-width modulation control scheme for maintaining a nearly constant output voltage, regardless of changes in input voltage and load current, thereby delivering the highest possible efficiency.
