The DRV103U/2K5 is a high-efficiency integrated, low-side power switch and load driver. It belongs to a family of Power Management ICs (PMICs) which is commonly used for power distribution switches and load drivers. This article will cover the application field and working principle of the DRV103U/2K5.

The DRV103U/2K5 is designed for applications such as DC/DC or AC-DC converters, battery powered systems, single end load switches and non-isolated supplies, which require high power switch current and low RDS(ON). The internal power switch is rated up to 2.5A and operates with a peak efficiency of more than 95% with adjustable current protection level.

The DRV103U/2K5 includes a wide range of integrated features to minimize design effort and minimize system cost. These include a fast and accurate one-shot pulse mode for fault protection, a simultaneous synchronous rise and fall gate drive capability, a PWM mode to reduce total system power consumption and adjustable current limit settings up to 2.5A.

The DRV103U/2K5 is a voltage-mode, high-side power switch and load driver. It features an integrated 5V source, the Synchronous FET, which is capable of switching up to 2.5A. The internal Synchronous FET is rated to switch up to 100V and has a low RDS(ON), thus providing high efficiency and low power dissipation.

The DRV103U/2K5 operates in pulse, PWM and constant on/off modes of operation. In pulse mode, the switch is enabled by an externally generated pulse signal and is automatically disabled whenever the pulse stops. The PWM mode is used to reduce the average operating power consumption and is initiated by a pulse signal. In this mode, the FET is enabled when the duty cycle of the pulse signal is greater than 50% and is disabled when duty-cycle is less than 50%. In constant on/off mode, the switch is enabled or disabled by an on/off signal and is controlled externally which may be generated by a microcontroller.

The DRV103U/2K5 also features an adjustable current limit setting up to 2.5A. This allows the user to set the maximum output current so that it is compatible with the load.In addition, the DRV103U/2K5 is protected from over-current, over-temperature, and under-voltage conditions. This prevents any damage to the system due to excessive power conditions.

The DRV103U/2K5 is an extremely versatile and cost-effective integrated power switch and load driver. It has a wide range of integrated features which makes it suitable for various industrial and automotive applications. Furthermore, its adjustable current limit setting and various protection features make it an ideal choice for applications where safety and reliability are important considerations.
