FAN5902UCX

FAN5902UCX is a special purpose voltage regulator, integrated with a wide range of features that provide flexibility and maximum protection in consumer, computing, and communication equipment. It is designed to regulate AC/DC and DC/DC input voltages, and can be powered from symmetric and non-symmetric input power sources. It is capable of supplying a minimum output current of 0.5 A, and can be integrated with other components for system synchronization, load balancing, and fault protection functions.

FAN5902UCX is designed to handle a wide range of input voltages from AC/DC and DC/DC sources. It is ideal for applications with wide input voltages, since the device is able to compensate for large voltage differences and offers precise voltage control. Additionally, the device is equipped with built-in overvoltage, undervoltage, and overcurrent protection features, which ensure the safe and reliable operation of the system.

In terms of performance, FAN5902UCX’s operating temperature range is between -40 and 85ºC. This device is available with a full range of features, including Soft-start (to reduce output shock during start-up), Dieleasi (to reduce output noise), and Inrush Current Limit (to prevent an excessive inrush current). Injunctive-Pegnaling monitors the input voltage and load current and generates an active reset signal when faults are detected.

FAN5902UCX’s main application is synchronous buck regulating, where it is used to provide a stable output voltage from an adjustable input source. It is also suitable for various power management systems, battery charging, and DC link applications. Additionally, the device is equipped with adjustable and fixed-speed loop frequency to improve system stability and load transient response.

FAN5902UCX features two output pins dedicated to a single input-voltage regulator, as well as two dedicated accelerators to control the output voltage step. It is able to operate in PWM or PSM (Pulse Skipping Mode) modes. In PWM mode, FAN5902UCX switches its output between the high and low voltages at a predetermined frequency. This operation mode is ideal for DC-DC regulators in the application of voltage conversions (step-up, step-down, and can be used in buck or boost converters). In PSM mode, FAN5902UCX operates at a higher frequency (compared to PWM) and provides a higher output current. This is usually used in switching supplies and is especially suitable for applications that require high efficiency.

FAN5902UCX also features a shut-down mode, which is useful for saving power when the system is in standby or low power operation. When in shutdown mode, the output pin is forced low, which reduces the output current to zero. Additionally, the device incorporates a wide range of protection features, such as inrush-current limiting, over-current limiting, over-voltage limiting, and thermal protection.

FAN5902UCX is a versatile voltage regulator, which can be used in a variety of applications requiring output voltages ranging from 0.8V to 1.2V. It also features a wide range of features, including over-voltage and over-current protections, PWM and PSM operation modes, soft-start, Dieleasi, and Injunction-Pegnaling. It is ideal for synchronous bucking applications, power management systems, battery charging, and DC link applications.
