LT3790EFE#TRPBF

The LT3790EFE#TRPBF from ADI Electronics is a versatile synchronous 4-switch buck-boost voltage/current regulator controller. It is designed to regulate output voltage, output current, or input current, with input voltages that can be above, below, or equal to the output voltage. This controller features a constant-frequency, current mode architecture, allowing its operating frequency to be adjusted or synchronized between 200kHz and 700kHz.

Key electrical specifications include a wide input voltage range from 4.7V to 60V. The output voltage accuracy is 2% for voltages between 1.2V and 60V, and the output current accuracy is 6% for voltages between 0V and 60V. It boasts synchronous switching for high efficiency, reaching up to 98.5%.

The LT3790EFE#TRPBF is suitable for various applications including voltage regulators, battery chargers, and super-capacitor chargers in automotive, industrial, and telecom systems. It provides input and output current monitoring and status flags such as C/10 charge termination and a shorted output flag. The device is housed in a 38-lead TSSOP package with an exposed pad, designed for surface mounting.

This controller is capable of handling 100W or greater per IC and can be easily paralleled to extend output power. It ensures VOUT is disconnected from VIN during shutdown and does not require a top FET refresh cycle in buck or boost operation.
