MAX16950CAUE/V+

The MAX16950CAUE/V+ is a versatile DC-DC switching regulator that is available in two versions, either as a standard voltage or as an adjustable one. It is one of the first integrated solutions that is specifically design to enable applications that need both highly efficient, low-voltage and high-voltage DC-DC regulation. This device operates with input voltages from 3V to 60V, and from 0.5V to 5.5V output, allowing for both low-voltage as well as high voltage power conversion.

Applications

The MAX16950CAUE/V+ is suitable for many different application fields, ranging from industrial and medical devices to telecommunication and automotive markets. Depending on the application, the MAX16950CAUE/V+ can be used as a step-down converter, a voltage-inverting boost regulator, or as a dedicated rail splitter. It provides up to 98% efficiency over a wide range of input voltages, making it suitable for battery-powered applications that require high efficiency.

The MAX16950CAUE/V+ also features many integrated features such as adjustable soft-start, precision enable, overvoltage protection (OVP) and gate protection circuitry, allowing users to reduce the design time and bill of material cost while maintaining the high efficiency ratings required in the applications.

Working Principle

The MAX16950CAUE/V+ follows the conventional buck-boost switching regulator principle, in which the output voltage is controlled by the duty cycle of the power switch. This device uses a low-side PFET as a series power switch, regulated by an integrated feedback PWM controller. The feedback voltage is converted to a duty cycle by an internal error-amplifier, and then applied to the gate of the power switch.

The MAX16950CAUE/V+ also features a soft-start feature, which limits the inrush current by ramping up the duty cycle slowly, allowing for a smooth start-up of the connected load. In addition, the MAX16950CAUE/V+ also features a precision enable function which allows the user to carefully control the turn-on and turn off transients.

The MAX16950CAUE/V+ also has several protection features that prevent it from damage in the event of voltage or current overloads. These protection features include overvoltage shutdown, overcurrent protection, short-circuit protection, and thermal shutdown.

Conclusion

The MAX16950CAUE/V+ is a versatile DC-DC switching regulator that is designed for efficient, low-voltage and high-voltage power conversion. It is suitable for many different application fields ranging from industrial and medical to communication and automotive markets. The device also features many integrated features and protection functions, such as adjustable soft-start, precision enable, overvoltage protection, gate protection circuitry and more, allowing users to reduce design time and BOM costs while still achieving excellent power efficiency and reliability.
