NCP612SQ15T1 - PMIC - Voltage Regulators - Linear

NCP612SQ15T1, developed by ON Semiconductor, is a series of linear voltage regulators designed for use in automotive, consumer and industrial equipment. It is a cost-effective solution that offers design flexibility and reliable operation in a compact, low-profile package.The NCP612SQ15T1 is a two-phase linear voltage regulator that provides a regulated output voltage of up to 15V with a maximum output current of 1.5A. It is rated for an input voltage range of 6-20V and works in temperatures between -40°C and 125°C.The device has a wide range of selectable operating modes that allow the user to select the most suitable position for their application. The settings available include adjustable output voltage, guard band current limit, over-temperature protection, output tracking, over-current protection and current fold-back. The NCP612SQ15T1 also supports a programmable soft-start/rise time and adjustable power-on delay/fall time.The NCP612SQ15T1 is available in a 10-pin TSOP or a 14-pin LLP package with a maximum height of 2.03mm. It also features a standby pin for reduced power consumption, which allows the user to reduce the operating current when the device is not in use.The NCP612SQ15T1 is designed for applications requiring a reliable voltage regulator. It is ideal for use in automotive applications such as engine control systems, navigation systems, power windows, and seat control systems. It could also be used in consumer and industrial equipment such as scanners and printers, medical equipment, and game consoles.The NCP612SQ15T1 voltage regulator follows the linear voltage regulator circuit principle, a simplification of the buck-boost circuit. A linear voltage regulator works by controlling the flow of current that is entering and leaving its associated circuit, so that the output voltage remains constant according to the regulation voltage. To regulate the output voltage, the device requires an input voltage slightly higher than the desired output voltage.The operation of the NCP612SQ15T1 is based on a series of positive feedback loops. First, an error amplifier generates a signal that is used to adjust the reference voltage level. This reference voltage then drives the series switch (a MOSFET) whose output voltage will be the same as the reference voltage. Depending on the input to output voltage ratio, the series switch will either be partially on (in step-down mode) or partially off (in step-up mode). The amount of current through the switch depends on the input voltage, which is effectively controlled by a feedback loop. Any excess current is discharged through the current sense resistor, which is also part of the feedback loop. The output voltage is then adjusted until the control loop\'s current demand is satisfied and the output voltage is stable. Overall, the NCP612SQ15T1 is an efficient and reliable solution for automotive, consumer and industrial applications that require a tightly regulated, low-profile voltage regulator. It is a cost-effective solution that offers the user high levels of flexibility and reliable performance.
