MAX766ESA+T Application Field and Working Principle
MAX766ESA+T is high-efficiency, low-noise, high-current, DC/DC buck switching regulator. By merging state-of-the-art 600kHz PWM controller with a highly integrated switch FET, this IC can greatly reduce overall size and complexity of the power supply design.
Introduction
The MAX766ESA+T is a nominal 3A switching regulator that produces a fixed, adjustable, or pulse-width modulated (PWM) output. It achieves a typical efficiency of up to 93%, enabling high power density and reducing power dissipation in the application. The MAX766ESA+T also features low-noise operation at low switching frequencies. The switching frequency can be adjusted from 300kHz to 600kHz to allow the designer to optimize the system for noise, size, efficiency, or cost.
Features
- 600kHz PWM frequency
- Up to 93% component efficiency
- Integrated 3A integrated switch FET MD
- Small SOT-23-6 package
- Adjustable output voltage
- 3.3V to 12V input voltage range
- Ramp compensation to reduce output voltage undershoot
- Output short-circuit protection
Applications
- Notebook and Tablet Computers
- Telecommunications devices and displays
- Embedded systems and Server load power
- Automotive and Battery Operated Systems
- Portable device power management
Pins Configuration and Working Principle
The MAX766ESA+T device is available in a 6-pin SOT-23 package with the following pin configuration.
- EN: Enable Input Pin
- FB: Feedback Input Pin
- VIN: Input Supply Pin
- GND: Ground Pin
- VOUT: Output Voltage Pin
- VSWIT: Switch Pin
The MAX766ESA+T switching regulator works by controlling the current through an internal power MOSFET switch to regulate the output voltage. When the internal switch is in on condition, the input voltage is applied across the inductor and energy is stored in the form of magnetic field. When the mid-MOSFET switch is transitioned to an off state, the magnetic energy stored in the inductor will be transferred to the output through the output capacitor. The size of the output capacitor and the switch frequency are of paramount importance for the output performance of the switch regulator.
Conclusion
The MAX766ESA+T is an ideal choice for any space-constrained design requiring high-efficiency and low-noise operation with 3A output capability. With its 600kHz PWM switching frequency and adjustable output voltage, the MAX766ESA+T offers an ideal solution for notebook and tablet computers, embedded systems, server load power and many other applications. Its integrated switch FET, adjustable output voltage and short-circuit protection features make it an ideal choice for power management solutions.
