Boost controller for legacy and low-volume builds
The Maxim Integrated MAX770CPA is a step-up (boost) DC-DC controller in an 8-pin DIP through-hole package. It drives an external transistor switch to generate a regulated positive output voltage higher than the input.
Lifecycle and compliance
The MAX770CPA is listed as Active in production, so there is no last-time-buy pressure for existing designs. The RoHS compliance status is non-compliant, which means the part contains lead (Pb) in the solder-dipped leads or die-attach. For designs that must meet RoHS exemption-free requirements, this part will not pass incoming inspection unless a specific exemption (e.g., lead in high-melting-temperature solder) is documented. For prototype runs, repair depots, or markets where RoHS is not enforced, the non-compliant status is often acceptable.
