It drives an external transistor — no synchronous rectifier on-chip — so the output stage is up to you. Supply range runs from 2.7 V to 15.5 V on Vcc/Vdd. Clock sync is built in. Output configuration can be positive or negative. ## Temperature grade and environment Rated 0°C to 70°C ambient — commercial temperature grade. ## Package and mounting 20-pin SSOP, 5.30 mm body width, surface-mount. That is a fine-pitch SOIC derivative — standard reflow profile, no exotic stencil. The supplier device package is 20-SSOP, same as the case code. No through-hole option here; plan for an SMT line or a hot-air station for rework. ## RoHS status matters Listed as RoHS non-compliant. That is a hard stop for any product sold into EU, UK, or California markets without an exemption. If your design is RoHS-mandated, you need an alternative or a documented exemption. If you are in a military or high-rel program that still allows tin-lead, this part is a fit — and the non-compliant status may actually be preferred for solder-joint reliability in leaded assemblies. ## Lifecycle and sourcing Product status is Active per the manufacturer — no last-time-buy notice, no NRND flag.","metaTitle":"MAX741UCAP Switching Controller, Buck/Boost, 2.7V-15.5V","metaDescription":"MAX741UCAP step-up/step-down switching controller from Maxim Integrated. 1 A, Buck/Boost topology, clock sync, 20-SSOP.
