Miscellaneous is a type of application field and its working principle is varied. In this article, we will introduce the AGP3503HMP-G1, its application field and working principle.

The AGP3503HMP-G1 is a high-power, microprocessor-controlled non-isolated buck-boost DC/DC converter module with very high efficiency. It is designed for automotive applications, with input voltage range from 4.5 V to 36 V. The output voltage is adjustable between 4.5 V and 27 V with output current up to 3.5 A (depending on the input voltage).

This buck-boost DC/DC converter module is specifically designed for automotive applications. It has many advantages over the conventional converters, which include fast turn-on response time, ripple cancellation and over temperature protection. Furthermore, it has a soft start feature that allows for current limiting during start-up to reduce inrush current. The module also provides pre-programmed functions for under-voltage protection, over-current protection and short-circuit protection, all of which protect both the converter and the system from damage.

The working principle of this module is based on the inductor-buck and capacitor-boost topologies, with an active-clamp reset to regulate the output voltage. The module utilizes an integrated PMOS MOSFET and series control method for the buck and boost functions. It also has a switchable current-sharing switch controller which is used to share the current between the buck and boost paths when there is a current demand from both path. The buck-boost DC/DC converter module can also be used as a current regulator by controlling the duty cycle of the output voltage.

In summary, the AGP3503HMP-G1 is a highly efficient, microprocessor-controlled non-isolated buck-boost DC/DC converter module for automotive applications. It has many advanced features and functions that can be used to protect the system and converter from damage. Its working principle is based on the inductor-buck and capacitor-boost topologies, along with an active-clamp reset to regulate the output voltage and a switchable current-sharing switch controller to share the current between the buck and boost paths.
