<p>The LT1961IMS8E#TRPBF (LT1961) is a high-performance synchronous step-down DC/DC converter available in DSU (DFN 6-pin thin shrink small) package and a variety of LT1961 packages. With an operating voltage range from 3.2V to 16V, the LT1961 provides up to 2.1A of output current. The LT1961 is suitable for a wide range of applications whose DC/DC conversion requirements don&amp;#39;t exceed the maximum current limit.</p><h2>LT1961IMS8E#TRPBF Applications</h2><p>The LT1961 provides a wide range of applications in cost sensitive, low power and space constrained applications. It is ideally suited for portable computing and communication devices, such as mobile phones and digital video cameras. Other typical applications include green energy and medical devices and automotive systems.</p><h2>LT1961IMS8E#TRPBF Working Principle</h2><p>The LT1961 is a low dropout regulator, providing power to the load with a minimum external voltage drop. The LT1961 is a synchronous step-down DC/DC converter. It has a wide operating voltage range from 3.2V to 16V, output current up to 2.1A, and typical efficiency up to 96%. It supports both fixed and adjustable output voltages. Its synchronous mode operation allows for even lower power consumption than its asynchronous mode, while still maintaining isolation between the input and output.</p><p>The LT1961 consists of an internal voltage regulator, a PWM controller and an internal power MOSFET. The PWM controller steps down the input voltage, adjusting the duty cycle to match the output voltage. The MOSFET switches the energy between input and output capacitors and dissipates the excess energy into the track. The internal voltage regulator is used to provide a stable voltage reference comparator reference voltage.</p><p>The LT1961 offers a low-noise high-efficiency solution for applications that require step-down DC/DC converters with small footprint and low parts count. Its features include adjustable current limit, thermal shutdown and short-circuit protection. The LT1961 also has a low maximum operating current (1.5A) and provides excellent transient response.</p>
