The LTC4357CDCB#TRPBF is a dual P-channel MOSFET that is ideal for applications such as synchronous buck converter, OR controllers, and ideal diodes. Its low on-resistance of 2.4 mΩ provides for very effective current sinking in buck, boost and ORing applications, allowing higher power efficiency in higher power applications. The device is capable of sink current up to 25A and supports up to 22V drain-to-source voltage.

The LTC4357CDCB#TRPBF is designed to provide an output signal with a MOSFET driver stage and a level-shifter stage with ESD protection. The output drive is designed to prevent undesirable signal glitches, so the signal is clean and steady. The output current can be adjusted with an external current source, allowing it to be optimized for different loads. The device also includes supply ripple rejection, making it ideal for applications with noisy supplies. The device is available in a small, 4mm x 4mm, 20-lead QFN package.

PMIC - OR Controllers

The LTC4357CDCB#TRPBF is ideal for PMIC - OR controllers. This type of controller makes use of over-current protection, and therefore, the device must be able to sink sufficient current when using a limited voltage range. The LTC4357CDCB#TRPBF can handle up to 25A, making it suitable for this application. The built-in supply ripple rejection also prevents unreliable current output, ensuring that the controller is able to operate reliably and accurately.

Ideal Diodes

The LTC4357CDCB#TRPBF is also ideal for use as an ideal diode, as it can handle up to 22V drain-to-source voltage. The device is particularly useful for applications that require high-voltage solutions, as the device is capable of handling up to 500V. The built-in supply ripple rejection also ensures that the output remains steady, even during high-voltage applications.

The device is also very efficient, as it is capable of handling up to 25A while operating on as low as 2.4 mΩ, resulting in effective current sinking capabilities. This makes it an ideal solution for applications where power efficiency is of paramount importance. The device is also available in a small, 4mm x 4mm, 20-lead QFN package, making it a very compact solution.

In conclusion, the LTC4357CDCB#TRPBF is an ideal device for applications that require high power efficiency, such as synchronous buck converters, OR controllers, and ideal diodes. Its low on-resistance, combined with its high current conditioning capability, makes it a very efficient solution. It is available in a small package, and its built-in supply ripple rejection makes it an ideal choice for high-voltage applications.
