The MAX8972BEWI+T is an integrated, single-phase synchronous step-down regulator IC with an internal high-side MOSFET and integrated dual-channel, configurable, over-current protection (OCP) with adjustable thresholds. It is suitable for providing regulated power supply to microprocessors, DSPs, and application-specific integrated circuits (ASICs) that require tight output voltage regulation tolerances across a wide ambient temperature range. The MAX8972BEWI+T features a two-cycle synchronous PWM control that enables fast transient response and low EMI/EMC performance. The device is ideal for applications that require PWM control from space-constrained applications, such as notebooks, tablets, netbooks, and embedded systems.

The MAX8972BEWI+T can be used to generate the regulated output voltage from a range of input voltages. The voltage feedback pin monitors the output voltage, and the error amplifier adjusts the pulse width modulation (PWM) duty cycl modulating wave according to the feedback signal. This enables the device to provide load regulation with minimum voltage droop across the entire range of load currents. The operating frequency of the device can be programmed with the feedback pin, allowing the device to easily meet the international EMI/EMC requirements.

The MAX8972BEWI+T features a robust integrated MOSFET with high power-density, which can switch up to 20A. The device also features an integrated dual-channel over-current protection (OCP) circuit with adjustable thresholds. This increases system protection while minimizing external components necessary in the design. Additionally, the device can detect an over-voltage, over-temperature, and short-circuit condition based on an adjustable OCP threshold.

The MAX8972BEWI+T can be used in a variety of applications. It is suitable for providing regulated power supply to microprocessors, DSPs, and ASICs that require tight output voltage regulation tolerances across a wide ambient temperature range. Additionally, it can be used in power supplies for mobile phones, PDAs, laptop computers, and other consumer or industrial systems.

In conclusion, the MAX8972BEWI+T is a highly integrated, single-phase synchronous step-down regulator IC with an internal high-side MOSFET and integrated dual-channel, configurable, over-current protection (OCP) with adjustable thresholds. The device is ideal for applications that require PWM control from space-constrained applications, such as notebooks, tablets, netbooks, and embedded systems, and it is suitable for providing regulated power supply to microprocessors, DSPs, and ASICs that require tight output voltage regulation tolerances across a wide ambient temperature range.
