Isolated Power Factor Corrected Offline Regulator Needs No Opto
Linear Technology Corporation announces the LT3798, an isolated flyback controller with single stage active power factor correction (PFC). A power factor of greater than 0.97 is accomplished by actively modulating the input current, eliminating the need for an extra switching power stage and associated components. In addition, no opto-isolator or signal transformer is required for feedback since the output voltage is sensed from the primary-side ...
36VIN, 600mA µModule Step-Down Regulator in 6.25mm x 11.25mm BGA Consumes only 5µA Quiescent Current
Linear Technology Corporation introduces the LTM8029, a 5µA quiescent current DC/DC step-down µModule regulator with very low dropout voltage and a wide input and output voltage range of operation. . Capable of delivering up to 600mA, the LTM8029 prolongs battery run time one to two key features: (1) 5µA quiescent current consumption during standby mode and only 0.9µA in shutdown discharges very little current from the battery, (2) very low 0...
24V, 15A Monolithic Synchronous Step-Down Regulator with Differential Output Sensing & Clock Synchronization
Linear Technology Corporation introduces the LTC3613, a high frequency controlled on-time synchronous step-down DC/DC converter with differential output voltage sensing and clock synchronization. The controlled on-time, valley current mode architecture enables a very fast transient response by increasing its operating frequency during a transient event, allowing the LTC3613 to recover from a large load step in only a few clock cycles.
36V, 3.5A, 2.4MHz Step-Down DC/DC Converter Requires Only 75µA of Quiescent Current & Operates with 150ºC Maximum Junction Temperature
Linear Technology has announced the H-grade version of the LT3680, a 3.5A, 36V step-down switching regulator with Burst Mode operation to keep quiescent current under 75µA. The LT3680 operates within a VIN range of 3.6V to 36V, making it ideal for load dump and cold-crank conditions found in automotive applications. The H-grade version operates up to a junction temperature of 150ºC, compared to the E and I versions' 125ºC maximum junction temp...
