FAN4860UC5X

The FAN4860UC5X is a pulse-width modulation (PWM) synchronous buck regulator designed to convert higher input Voltage sources to lower output Voltage levels with high efficiency. This versatile device can be used for applications including powered sources for VGA cards, cellular phone standby power, game console systems, laptop computers, instrumentation and medical devices. Additionally, this series of Voltage regulators provide extensive features to support system needs.

The synchronous design improves the efficiency of the regulator by eliminating the body diode associated with most buck converters. With synchronous rectification, both high-side and low-side MOSFETs are switched on during any load condition while the outputs of the regulator do not exceed the input voltage. The FAN4860UC5X series features built-in Soft-Start and a low-side short-circuit protection voltage monitor (SCP).

The FAN4860UC5X series is available in four output Voltages (1.8V, 1.5V, 1.3V and 0.7V) with a maximum output current of 3.2A (at 1.8V), 5.4A (at 1.3V) and 4.0A (at 0.7V) and adjustable output down to 0.2V above ground. It also features a shut down mode to conserve power in no load conditions. Performance-wise, the device has a current mode topology, which ensures fast transient response to load changes; load regulation of 0.5% (20 mV typical at full load); temperature tracking or emulated NTC compensation; and fast transient response of less than 5% over 0 to 3.2A load range.

At the heart of the FAN4860UC5X series is an advanced low voltage integrated circuit designed to regulate the output Voltage at the required level. It uses pulse-width modulation (PWM) technology to optimize the output Voltage in a variety of operating conditions. During any load condition, this PWM switching regulator will hold its output Voltage within the specified limits by accurately controlling the frequency and duty cycle of the output.

The FAN4860UC5X series of Voltage regulators also features external ON/OFF control, programmable soft-start and short-circuit protection. This makes it ideal for powering FSMs, microprocessor-based systems, general purpose instrumentation, medical devices, and applications involving high power. Additionally, it offers low output voltage ripple and noise, fast transient response and high efficiency over the full load range.

In conclusion, the FAN4860UC5X series of Voltage regulators is an excellent choice for various applications requiring a wide range of output Voltages and currents. It can be used to power FSMs, microprocessor-based systems, general purpose instrumentation, medical devices and applications involving high power. Moreover, it offers fast transient response and programmable features that further enhance its performance.
