LTC1700EMS#PBF Application Field and Working Principle
The LTC1700EMS#PBF is part of the PMIC – Voltage Regulators – DC DC Switching Controllers family, specifically a micro-power adjustable frequency step-down switching regulator. In this article, we\'ll be discussing its typical applications and its underlying operating principles.
Basic Application
The LTC1700EMS#PBF typically sees use in a wide variety of applications. It operates by harvesting energy from the input capacitors, and then works to convert this energy into a regulated output voltage. The primary use cases for this component includes;
- Battery-powered computing applications – the LTC1700EMS#PBF is capable of providing a low power operating mode and has a wide input voltage range.
- High efficiency and high ripple converter applications – its internal MOSFETs and control circuitry offer high efficiencies and low ripple.
- Sensor supply and system power sequencing applications – its adjustable frequency feature enables the creation of precise sequencing.
Furthermore, its wide operating temperature range and monitored power-good indicator also have vast applications in industrial, automotive, and medical applications.
Working Principle
The LTC1700EMS#PBF works on an adjustable frequency, step-down switching regulator design. The current mode architecture of this switching regulator ensures fast transient responses and helps to eliminate surges and excessive current to the input capacitors. The DC-DC converter can be configured to operate in either the Burst Mode® or pulse-skipping mode, depending on the application requirements. This adjustable frequency design ensures that optimal efficiency is achieved at a given load.
The external PWM signal can be used to control the power ramp-up time, as well as the internal frequency, of the LTC1700EMS#PBF. This allows it to be set up to provide precise load or system power sequencing. It also has a programmable, low power mode which allows the switching regulator to provide lower power consumption when the load is low or the system is in standby.
The LTC1700EMS#PBF also features an external power good indicator with an adjustable timeout window. This makes it easier to check the status of the device or enable remote power shutdown if the power delivery is unsuccessful.
Conclusion
The LTC1700EMS#PBF is part of the PMIC – Voltage Regulators – DC DC Switching Controllers family and finds use in many applications from industrial, automotive, to medical use. Its adjustable frequency capability and programmable low power mode make it quite versatile for a variety of applications. Its current mode architecture also helps to provide surge and ripple control, which leads to a more reliable output. Plus the external power-good indicator provides an easy way to check the operation of the device.
