PMIC – Voltage Regulators – DC DC Switching Regulators

The LTC3410ESC6–1.875#TRPBF is one of the many DC DC switching regulators available in the market. This device is able to regulate an input voltage to the desired voltage setpoint. This regulator has a wide operating temperature range and features an integrated switching regulator and a patented current limit control loop. It is also capable of delivering high levels of output current with a wide range of duty cycles.

The LTC3410ESC6–1.875#TRPBF is ideal for applications in industrial, commercial, and even automotive areas. It is able to regulate voltages of up to 2.5V with an accuracy of ±0.2V. In respect to its power consumption characteristics, the LTC3410ESC6–1.875#TRPBF requires a minimal external input voltage of 4.5Vdc, a quiescent current of 1mA, and a total power dissipation of around 3W. An adjustable voltage output is achieved through the feedback pin connected to an external voltage-divider.

The LTC3410ESC6–1.875#TRPBF features a 0.6MHz switching frequency, allowing for tighter output power supply noise filtering in comparison to other achievable frequencies. Additionally, the device supports a built-in Soft-Start functionality which safely ramps up the output voltage with a programmable current limit. This feature helps ease the system-level requirements in the startup stage, and helps protect the device against over-current during power up.

The LTC3410ESC6–1.875#TRPBF includes internal compensation which makes its use easier, without having to adjust additional external components. It also has internal frequency compensation which helps reduce the output ripple, improve efficiency, and reduce electromagnetic interference. Besides, the device also provides a logic-controlled shutdown, allowing the user to reduce power consumption when the device is not in use.

The LTC3410ESC6–1.875#TRPBF includes the adjustable current limit capability. This feature enables the user to adjust the maximum output current for each look-up table. Additionally, the device features an over-voltage protection, which prevents damage from an unexpected increase in the input voltage. In case of a shorted output condition, current will be limited to the programmed level which helps protect the gate drivers from damage.

The LTC3410ESC6–1.875#TRPBF also has a soft-start time-out feature. This feature prevents the switching regulator from exceeding the programmed level of output current. Additionally, the device features a synchronous rectification feature which helps improve efficiency. This is achieved by switching the synchronous rectifier to the same switching frequency as the internal power stage.

The LTC3410ESC6–1.875#TRPBF is primarily used in applications where the output voltage has to be adjustable between 2.5V-40V in automotive, industrial, commercial and similar areas. It can be used to regulate voltage levels of power supplies and other devices which require an adjustable input voltage. Additionally, the device can also be used as a dual power supply with adjustable current limits, thus increasing the reliability of the system. In addition to its adjustable voltage output capabilities, the device also provides several benefits such as short circuit protection, over-voltage protection, and current limit protection.
