S-882142AMH-M2RTFU is part of a comprehensive integrated power module that combines power elements, integrated passive components (IPCs) and control circuitry on a single chip. It is a complete power management solution that can provide up to 62 watts of power with highly efficient voltage conversion and heating, saving space in applications ranging from mobile phones and accessories, to tablets and computing equipment. The S-882142AMH-M2RTFU is a DC/DC Switching Regulator that operates in the input voltage range of 4.5V to 24V. It is a regulated, step-down intermediate dc-dc converter ideal for automotive, industrial and telecommunications applications.

The working principle of the S-882142AMH-M2RTFU is to step down the input voltage to a predetermined and constant output voltage that is needed by the application. The device’s high-side and low-side NMOFETs, controlled by a single integrated driver, form the main power stage. The load current and output voltage are precisely regulated by the controller. The regulation is achieved by adjusting the duty cycle (or frequency) of a symmetric PWM ramp waveform that is generated by the integrated oscillator. The symmetry of the waveform is ensured by the low-side gate driver bias, also generated by the oscillator. Feedback from the output voltage is synthesized to adjust the duty cycle, ensuring accurate and consistent output voltage. The current limiting of the S-882142AMH-M2RTFU is based on timing, with a fixed protective duty cycle for over current protection (OCP).

The S-882142AMH-M2RTFU offers many advantages in terms of its efficient and accurate regulation, wide input and output voltage ranges, adjustable frequency range, low dropout voltage, and low quiescent current. It is also capable of regulating an output voltage as low as 0.5V, allowing it to be used in a wide range of applications such as mobile phones, tablets, industrial equipment, automotive systems, and communication systems. The device also provides a wide range of over current protection (OCP) options that includes both adjustable and fixed protective duty cycles, allowing you to configure the device to protect your system from overloads or short circuits.

In summary, the S-882142AMH-M2RTFU is a highly efficient DC/DC Switching Regulator that is a complete power management solution for a wide variety of applications. By driving its high and low side NMOFETs with a single integrated driver and regulating the output current and voltage with an oscillator generated symmetric PWM waveform, the S-882142AMH-M2RTFU provides a versatile, high performance solution for a wide range of applications.
