PMIC (Power Management Integrated Circuits) broadly refers to a type of integrated circuits that can provide the power needed for different types of electronic products. It can be divided into many subcategories, one of which is voltage regulators, which are intended for the regulation of voltages. Voltage regulators can be further divided into two categories: linear regulators and DC-to-DC switching regulators. LTC3624EDD-23.3#TRPBF is a DC-DC switching regulator that can provide stable currents in applications needing circuit inputs. This article will discuss the application field and working principle of this device.

Application Field

The LTC3624EDD-23.3#TRPBF is a 3.2A Buck Regulator with low noise, making it suitable for high-performance applications. It operates with a 10V to 36V input voltage range and provides an output voltage as low as 0.6V. This regulator features a wide selection of protection features, such as short-circuit protection and thermal shutdown. It also has a low standby current when in shutdown mode, making it ideal for battery-powered applications. Additionally, its high performance and wide input voltage range make it suitable for applications in automotive, industrial, and consumer products.

Working Principle

The LTC3624EDD-23.3#TRPBF is an integrated, monolithic voltage regulator that utilizes a synchronous rectifying step-down architecture. It has a wide input voltage range and can provide a regulated output voltage of up to 2.5 V. This device also offers a wide range of operating frequencies and can be synchronized to an external clock signal if desired.

The LTC3624EDD-23.3#TRPBF contains two internal power MOSFETs driven by the two internal control loops to control power conversion. Internal control loops are responsible for setting the output voltage and regulating the output voltage under light or no load conditions. The device can also be configured as a low-noise generator by setting a certain frequency.

The LTC3624EDD-23.3#TRPBF also features an adjustable soft-start circuit, which can be programmed for a specific amount of time for starting up. This helps in preventing the large inrush currents during start-up and protects components from over-voltage or current stress. Additionally, it contains a low voltage lockout and thermal shutdown for enhanced protection.

Conclusion

The LTC3624EDD-23.3#TRPBF is a DC-to-DC switching regulator that can provide stable currents in applications needing circuit inputs. It operates with a 10V to 36V input voltage range and provides an output voltage as low as 0.6V. It contains two internal power MOSFETs, an adjustable soft-start circuit and various protections. This makes it suitable for applications in automotive, industrial, and consumer products.
