42V Triple Monolithic Synchronous Step-Down Regulator
The LT®8601 is a triple channel, current mode, monolithic buck switching regulator with a programmable power-on reset. All regulators are synchronized to a single oscillator with an adjustable frequency from 250kHz to 2.2MHz. The LT8601 can be configured for micropower Burst Mode or Pulse-Skipping operation at light load. Micropower operation results in quiescent current of 30µA with all three regulators operating as shown in the application below with no load applied. The high voltage channels are synchronous buck regulators that operate from an input of 3.0V to 42V. The output currents are up to 1.5A (OUT1) and 2.5A (OUT2). The low voltage channel operates from an input of 2.6V to 5.5V. In...

High Efficiency 42V/120mA Synchronous Buck
The LT®8604/LT8604C is a compact, high speed synchronous monolithic step-down switching regulator that delivers up to 120mA to the output with high efficiency at a constant frequency, even up to 2.2MHz. It accepts a wide input voltage range up to 42V and consumes only 2.5µA of quiescent current when operating in Burst Mode. Top and bottom power switches are included with all necessary circuitry to minimize the need for external components. The LT8604C includes BST and INTVCC ceramic capacitors for a more compact solution while having SYNC/ MODE and HYST pins. The SYNC/MODE pin selects the regulator’s operation between forced continuous mode, for predictive interference in sampling systems, ...

750mA Synchronous Step-Down Regulator
The LT®8607 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes only 1.7µA of non-switching quiescent current. The LT8607 can deliver 750mA of continuous current. Burst Mode operation enables high efficiency down to very low output currents while keeping the output ripple below 10mVP-P. Internal compensation with peak current mode topology allows the use of small inductors and results in fast transient response and good loop stability. The EN/UV pin has an accurate 1V threshold and can be used to program VIN undervoltage lockout or to shut down the LT8607 reducing the input supply current to 1µA. The MSOP package includes a SYNC pin t...
