Analog comparators and hysteresis
A standard system requirement is to use the result of a simple “A vs. B” comparison as a basis for decision-making. For example, if the temperature is above a setpoint, turn the heat source off; and if the temperature is below that setpoint, turn the heat source on. Or perhaps there’s an alarm to sound […]
High-power-density synchronous buck converter sports 25-nsec minimum on time
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC7150S, a 20V, 20A monolithic synchronous buck converter with differential VOUT remote sensing. The device’s unique phase lockable controlled on-time constant frequency current mode architecture eases compensation and is ideal for high step-down ratio applications that operate at high frequencies while demanding fast transient […]
