Introduction

LT3501EFE#TRPBF is a DC DC switching regulator from Linear Technology and is one of the lowest IQ buck ICs available in the market. It is designed to provide miniature size and wide input voltage, making it suitable for a variety of applications. The device comprises of a PWM controller, a high current power MOSFET, a frequency compensation network, and a power sense resistor. It operates from an input voltage range of 4V to 90V and can provide up to 2A of output current while operating at a switching frequency up to 1.3MHz.

Application Field

LT3501EFE#TRPBF DC DC switching regulator is mainly used in the following applications:
  • Industrial Equipment
  • Household Electronics
  • Medical Equipment
  • Instrumentation & Measurement
  • Communication Systems
  • Portable Electronics
  • Automotive Electronics
The LT3501EFE#TRPBF DC DC switching regulator is particularly suitable for applications that require very low quiescent current, like battery operated systems. The device can be used in non-synchronous buck-mode operation, which makes it ideal for applications that require high efficiency, such as powering radiators in cars.

Working Principle

The LT3501EFE#TRPBF DC DC switching regulator works on the principle of pulse width modulation (PWM). In this method, the output voltage is regulated by controlling the on-off ratio of the switches in the power circuit. This is achieved by applying a square wave signal to the switches in the power circuit. The ratio of the on time to the off time of the square wave is fixed by the control circuit so that the average voltage is kept at the desired level.The LT3501EFE#TRPBF DC DC switching regulator includes a high current N-channel MOSFET with a series power sense resistor and a frequency compensation network for controlling the voltage. The voltage is fed back to the controller to ensure accurate and stable output voltage under varying load conditions. The LT3501EFE#TRPBF also features cycle-by-cycle current limit and over temperature protection for safe operation.

Conclusion

To conclude, the LT3501EFE#TRPBF DC DC switching regulator from Linear Technology is one of the lowest IQ buck ICs available. With its miniature size and wide input voltage, this device is suitable for applications requiring very low quiescent current like battery operated systems. The device is ideal for applications like powering radiators in cars and includes additional features like current limit and over temperature protection for safe operation.
