Its 100% maximum duty cycle allows pass-through operation when the input voltage exceeds the target output, a useful feature for battery-powered systems where the input sags below the regulated rail. The controller drives external N-channel MOSFETs in a synchronous rectifier configuration, which improves efficiency over a diode-based boost by recovering the forward-drop loss. This matters for designs where every percent of efficiency extends battery runtime — think portable instruments, automotive pre-boost stages, or industrial sensor nodes running from a 12V or 24V bus. Switching frequency is programmable from 100kHz to 3MHz via a single resistor, letting the designer trade off inductor size against switching losses. At the low end, larger magnetics but better efficiency; at the high end, a smaller footprint but more heat in the FETs and controller. ## Package, thermal, and layout notes for the 16-MSOP-EP Housed in a 16-lead MSOP with an exposed pad (16-MSOP-EP), the LTC7804IMSE#PBF requires a thermal land on the PCB to sink heat from the die. The exposed pad is the main thermal path — without a proper via array to a copper plane, the junction temperature rises quickly under continuous load, especially at higher switching frequencies. Shipped in a Tube, not tape-and-reel — plan for manual or low-volume pick-and-place. If your line runs high-volume reels, factor in a tube-to-reel transfer or order the tape-and-reel variant if one exists. ## Active lifecycle and compliance — no end-of-life pressure RoHS3 compliant (RoHS exemption status not specified beyond the compliance statement), which covers EU and most global BOM requirements without the need for an exemption review. ## How it compares to the LTC3814EFE-5#PBF boost controller The closest functional peer in the ledger is the LTC3814EFE-5#PBF. Both are synchronous boost controllers with a single output, positive configuration, and transistor-driver output. The LTC3814 adds control features (Enable, Power Good, Soft Start) that the LTC7804 does not list in its spec table — if your design relies on a dedicated Power Good flag or a sequenced soft-start, the LTC3814 may be a better fit. The LTC7804's supply range (4.5V to 40V) matches the LTC3814's (4.35V typical), and both operate over the same -40°C to 125°C junction temperature range. The LTC7804's switching frequency range (100kHz to 3MHz) is wider than the LTC3814's fixed-frequency options, giving more flexibility for inductor selection. Package difference: the LTC7804 comes in 16-MSOP-EP, while the LTC3814EFE-5#PBF uses a 20-TSSOP-EP. The pinout and footprint are not compatible — a board spin is required to swap between them.","metaTitle":"LTC7804IMSE#PBF Boost Controller, 4.5-40V, 100kHz-3MHz","metaDescription":"LTC7804IMSE#PBF low IQ synchronous boost controller from Analog Devices.

At lower frequencies, inductor size increases but switching losses drop — better for efficiency-critical designs. At higher frequencies, the inductor and output capacitor shrink, but the MOSFET gate-drive losses and controller thermal dissipation rise.
