The LT1764ET#06PBF is a PMIC - Voltage Regulators - Linear that provides a low-cost, low-power solution for a wide range of applications which require step-down DC/DC conversion. Featuring a wide 2V to 15V input voltage range, the device can easily deliver up to 2A of continuous current with up to 0.6% accurate current regulation and wide load range from 1.6V to 14V output. The LT1764ET#06PBF is an adjustable, high frequency, high efficiency switching regulator – able to produce over 91% conversion efficiency for high current load applications. It offers the convenience of an integrated synchronous rectifier, and is equipped with an internal 0.8V reference. The device is highly configurable, with adjustable line, load and thermal regulation at a user selectable frequency of 300kHz, 600kHz and 1.2MHz.

The LT1764ET#06PBF is designed to work at a supply voltage of 4.15 V to 17 V. The device typically operates within a range of 0.8 V to 15 V and provides up to 2 A of output current. The LT1764ET#06PBF device can be used in many applications such as medical equipment, battery-powered devices, notebook computers, cellular phones, LCD displays andconsumer electronics. Its features include adjustable line, load and thermal regulation at a user selectable frequency of 300 kHz, 600 kHz and 1.2 MHz. The device can also be used for providing regulated and low noise power supplies.

The LT1764ET#06PBF operates as a synchronous buck regulator. The switching regulator is based around an N-channel MOSFET controller driven by an internal oscillator and a frequency compensation network. The high frequency operation allows use of small inductor and capacitor values, as well as small printed circuit boards. The LT1764ET#06PBF has dynamic line and load regulation with over current and over temperature protection. The protection limits the maximum output current and prevents overshoot or undershoot of the outputs in case of unexpected conditions such as short circuit or open loop. The LT1764ET#06PBF also includes a thermal shutdown circuit, which will turn off the output when the junction temperature of the device reaches its limit.

The LT1764ET#06PBF features an adjustable soft-start circuit that eliminates the inrush current on start-up. An external capacitor is used to set the time delay from start up to the final output voltage. The soft-start also serves to reduce output voltage noise when the regulator is put into and out of use. The device operates in forced PWM mode to improve load transient response for load changes up to 40%.

In order to reduce electromagnetic interference, the output voltage ripple can be reduced if a capacitor of a suitable value is connected between the Sensepin and the input pin. The output voltage ripple can also be minimized by having a small capacitor between the ground and the Input pin.

The LT1764ET#06PBF is ideal for applications where low cost, low power and high efficiency requirements are paramount. Its wide input voltage and output ranges make it suitable for a variety of applications including step-down DC/DC conversion. The device offers high efficiency, adjustable current regulation and soft-start, making it a great choice for battery-powered systems.
