Most portable electronic devices require power sources to remain operational — this is accomplished through an array of power management integrated circuits (PMICs). These components transform and deliver electrical energy from a variety of power sources, and help optimize overall system performance. Power conversion and regulation is typically handled by DC/DC (direct current to direct current) buck-boost switching regulators, which reduce, increase, or invert DC voltages with minimal insertion losses.

NCV896530MWTXG is one such example of a DC/DC switching regulator, offering high efficiency and low noise operation, as well as both fixed and adjustable voltage configurations. With an operating voltage between 4.5 V and 36 V, it is suitable for most automotive applications, including AFE (analog front-end) power supplies, active device control systems, and industrial programmable logic controllers.

In terms of its application field, NCV896530MWTXG is suitable for a broad range of general-purpose applications — it can be used as a power supply for microprocessors, memory and FPGA circuits, or motor drivers, as well as an energy harvesting interface. The RMS current of 8 A, the peak current of 16 A, and the maximum duty cycle of 0.9 all provide more than enough for most tasks.

The regulator is designed to work with a switching frequency of 1.2 MHz and is capable of supporting a wide input voltage variation. With its integrated gate drivers, output voltage overshoot and cross conduction are minimized. Its built-in thermal shutdown feature and short-circuit protection also offers comprehensive protection when under extreme temperatures or adverse conditions.

Typical power supply circuits require a range of control loops, and NCV896530MWTXG is no exception — the components within the integrated circuit are designed to transfer energy from the input stage to the output stage. To do this, a buck-boost signal generator is used to adjust the duty cycle at each switch within the circuit. By altering the switching sequence, the output voltage can be adjusted efficiently and accurately.

The IC operates in discontinuous conduction mode (DCM) and is able to generate an output voltage that is higher or lower than the input voltage. It also features synchronous current-mode control for accurate regulation, and its transfer-function output voltage regulation accuracy of ±2% provides tolerance even under extreme temperature variations.

NCV896530MWTXG is a highly efficient DC/DC switching regulator suitable for a number of general-purpose applications. It is capable of reducing, increasing and inverting DC voltages with minimal insertion losses, and provides high efficiency and low noise operation. With its integrated gate drivers, output voltage overshoot and cross conduction are further reduced, while its built-in thermal shutdown feature and short-circuit protection offer additional robustness. Thanks to the IC\'s design, power is efficiently transferred from the input stage to the output stage, and with its high accuracy ±2% output voltage regulation and support for a wide input voltage variation, this component offers reliable and high-quality performance for a range of automotive applications.
