The LTC3775IUD#TRPBF by Analog Devices is a High Frequency Synchronous Step-Down Voltage Mode DC/DC Controller. This electronic part is designed to provide a high frequency, power efficient, and low ripple voltage conversion solution for a wide variety of distributed power rail applications. The device utilizes an adjustable PWM control loop to accurately and efficiently step-down input voltages to an adjustable regulated output voltage as low as 0.6V. The low voltage output is regulated by the internal precision voltage reference, which is accurate within ±2%. The highly efficient switching architecture uses Synchronous Rectified Buck Converters to achieve peak efficiency of up to 96%. It also incorporates various features such as adaptive on-time (AOT) control, cycle-by-cycle current limit, line feed forward, power good overload protection, and programmable soft-start. The device is supplied in a tiny 5-lead, Pb-free, thermally enhanced TSSOP package that has an operating junction temperature range from -40°C to 125°C.
