DC DC Converters

DC-DC converters are electronic components that convert a direct current (DC) voltage from one level to another. These devices are essential in applications with multiple voltage sources, such as batteries, automotive, renewable energy systems, and those used in industrial processes. A DC-DC converter is an electronic device that converts electrical energy from one form to another. In this case, the voltage is converted from one DC voltage to a different DC voltage.

IV0503S application field and working principle

The IV0503S is a single-output DC-DC converter designed to meet a broad range of aerospace, automotive, railway, medical, and industrial applications. It can be used in a variety of applications such as commercial and military aircrafts, avionics, power-over-Ethernet (POE), portable device charging, LED lighting, and robotics. The maximum input voltage of the IV0503S is 30V and features a wide input voltage range from 9.5V to 30V. The converter can provide up to 2.5A of output current over a wide output voltage range from 0.6V to 30V. The IV0503S offers high efficiency, low ripple noise, built-in protection and has immunity against EMI and transient phenomena.

The device is a non-isolated boost converter with integrated synchronous rectification. It operates at a fixed switching frequency, so the input filter requirements are relaxed. The converter uses a switched-mode control technique to regulate the output voltage and features current-mode operation. The current-mode control provides fast response to load transients with excellent “line-load” regulation. It also features wide programmability and protection functions.

The IV0503S can operate in either continuous conduction or discontinuous conduction mode depending on the load range. While operating in continuous conduction mode, it allows for high efficiency over a wide load range. The device is also designed with built-in protection features such as short-circuit protection, overload protection, over-temperature protection, and under-voltage lockout.

The IV0503S is a versatile product with both analog and digital programmability, making it ideal for standard and custom applications. The device is available in several package options including a DIP, SMD, and QFN package.
