The NCV890130MWTXG is a member of the DC DC Switching Regulators module of Voltage Regulators manufactured by ON Semiconductor. This module is a high-efficiency, synchronous buck-boost voltage regulator, capable of supplying up to 1.3A of output current over a wide input voltage range from input voltages of 3V to 38V. It also allows for ultra-low quiescent current and power dissipation for power conservation.

This module features many features which make it easier to use in various application fields, including high-accuracy output voltage regulation, adjustable output voltage of 1.224V to 26.5V, small number of components, wide input voltage range, and high efficiency. This module is ideal for use in automotive, consumer and industrial applications, with a small solution size and high efficiency, making it a great choice for a variety of power needs.

The module uses Pulse Width Modulation (PWM) to regulate the output voltage. It also incorporates a low drop-out (LDO) regulator over the input voltage range to provide more efficient regulation. In order to meet the demanded output voltage, the PWM controller adjusts the duty cycle of the power switches to control the output voltage. The PWM adjusts the duty cycle such that there is enough current to turn on the power switches and maintain the regulated output voltage.

The PWM is able to operate over a wide frequency range from 100kHz to 2MHz. This range is adjustable by a current sense resistor and enable pin, allowing for an increased flexibility during operation. The inductive peak current limit can also be set with the current sense resistor for optimization under various load conditions.

The module also features internal linear and soft-start regulators to provide a smooth startup sequence with precision output voltage regulation during any application condition. Additionally,an adjustable soft start prevents inrush current to ensure effective operation of the power source.

The module features various protection features, such as thermal shutdown and over-voltage protection, to prevent damage due to excessive current or temperature. It also features under-voltage lockout, which prevents it from starting up when the input voltage is too low.

Overall, the NCV890130MWTXG is an ideal solution for a variety of applications across automotive, consumer and industrial needs. The wide input voltage range and high efficiency makes it an ideal choice, while the adjustable PWM operating frequency, low drop-out regulator and adjustable soft-start provide the user with more flexibility and precisionover their output voltage regulation.
