The LTC3525LESC6-3#TRPBF is a synchronous DC/DC buck (step-down) regulator specifically designed to deliver high current at low output voltages while offering 96% power efficiency. The step-down regulator features a fixed frequency continuous conduction mode (CCM) operation, an externally-programmable output voltage and adjustable current limit. The maximum switching frequency of the device is up to 2.5MHz, and the internal regulator works at environmental temperatures ranging from -40°C to +85°C.

The purpose of the LTC3525LESC6-3#TRPBF is to regulate the output voltage from a supply that is higher than the desired output voltage. The device works by taking the input voltage, then converting it via an internal switch. The switch then passes the voltage through an inductor and dumps the excess energy into a capacitor, which then regulates and outputs the correct voltage. The switch then starts over again to regulate the output voltage.

For example, when used to power an FPGA, the LTC3525LESC6-3#TRPBF can power the core and several other peripherals and can save board space using a combination of voltage sequencing, sequencing and sequencing control. The regulator also features a soft-start, and programmable current limit which protects against overloads. Soft-start can be used to limit in-rush currents, which can prevent malfunction with sensitive, high-power ICs.

The LTC3525LESC6-3#TRPBF also features a power good signal (PG) which is used to indicate when the regulator starts up and when the output voltage rises to within 1V of the set voltage. This signal can be used to inform the system when to begin operating. The device also has three logic-level enable inputs, which can be used to independently power either two or all three outputs.

Overall, the LTC3525LESC6-3#TRPBF offers a high level of efficiency, in addition to its numerous features, making it an ideal choice for applications requiring precise power management. From small-scale automotive systems to large-scale industrial applications, the LTC3525LESC6-3#TRPBF offers an efficient and feature-rich option for DC/DC buck regulators.
