Each output is adjustable down to 0.6 V, and the switching frequency spans 400 kHz to 4 MHz — wide enough to let you pick between small inductors (high frequency) and better efficiency (lower frequency). The 24-TSSOP with exposed pad pulls heat into the PCB plane; for two 3 A rails in that footprint, the thermal design needs a decent copper pour underneath. ## Temperature range — -55°C to 150°C Rated for junction temperature from -55°C to 150°C, this part fits military, avionics, satellite, and downhole equipment where the ambient can swing well beyond industrial limits. The 150°C TJ max also gives headroom in a hot enclosure — useful if the regulator sits near a processor or in a sealed motor-drive compartment. ## Synchronous rectification and external compensation Synchronous rectification is built in, so no external catch diode — that saves a component and keeps efficiency up at low output voltages. The part does require external compensation (loop stability components); it is not a fixed-frequency, internally-compensated part. Plan for a few passives around the feedback and compensation pins. ## Sourcing and lifecycle The LTC3615IFE#PBF is listed as Active with ROHS3 compliance.","metaTitle":"LTC3615IFE#PBF Dual Buck Regulator, 3A, 24-TSSOP","metaDescription":"LTC3615IFE#PBF dual step-down regulator, 3A per channel, 2.25V-5.5V input, 400kHz-4MHz switching, -55°C to 150°C.
