LTC3824HMSE#TRPBF - High Voltage Step-Down DC/DC Controller

The LTC3824HMSE#TRPBF is a high-performance step-down DC/DC controller from Linear Technology, designed to drive an external power MOSFET at frequencies up to 500kHz. This compact and efficient controller is suitable for a wide range of power supply applications, particularly where a high input voltage and a low output voltage are required.

With an operating input voltage range of 3.5V to 60V, the LTC3824HMSE#TRPBF is capable of withstanding high voltage transients, making it ideal for automotive, industrial, and telecommunication systems. Its low minimum on-time of only 100ns allows for high step-down ratios at high frequencies, which is beneficial for applications requiring a fast transient response.

The device features a powerful 1.1Ω on-chip MOSFET gate driver, enabling it to drive large power MOSFETs with ease. This feature helps in reducing the overall solution footprint by allowing the use of smaller, lower-cost external components. Moreover, the LTC3824HMSE#TRPBF offers excellent regulation and accuracy with its ±1% output voltage accuracy over the full temperature range.

One of the key advantages of the LTC3824HMSE#TRPBF is its constant-frequency current mode architecture, which provides excellent line and load transient response. Additionally, it includes a range of protection features such as overvoltage protection, undervoltage lockout, and a foldback current limit, all of which contribute to the safe operation of the end application.

Other notable features include programmable soft-start to control the turn-on time and minimize inrush current, a power good output signal for output voltage monitoring, and frequency synchronization capability to reduce RF interference in noise-sensitive applications.

The LTC3824HMSE#TRPBF is available in a thermally enhanced MSOP-16 package, which ensures efficient heat dissipation and reliable operation even in environments with elevated temperatures. With its combination of high performance, robust protection features, and compact size, the LTC3824HMSE#TRPBF is a versatile choice for engineers looking to design efficient power management systems.
