Product details

What the ratings mean for the BOM

The 300kHz switching frequency is fixed — no external sync or frequency adjust pin. That simplifies the BOM (no timing resistor or capacitor), but it also fixes the inductor value and output capacitor ESR target.

Temperature grade and environment

Rated for -40°C to 85°C ambient, the MAX774EPA+ fits industrial control cabinets, outdoor telecom shelters, and test equipment that sees seasonal temperature swings.

Sourcing and lifecycle

Listed as active with no last-time-buy notice. ROHS3 compliant. The 8-PDIP package is a mature, widely stocked form factor — no package-end-of-life concerns typical of some older DIP parts.

Frequently asked questions

Can MAX774EPA+ be used for a negative buck-boost application?

Yes. The MAX774EPA+ is specifically configured for negative output generation. The output configuration is negative, and the topology is buck-boost. It drives an external transistor (P-channel MOSFET or PNP) to regulate a negative voltage from a positive input rail.

What is the closest pin-compatible alternative to MAX774EPA+ in this component family?

Within the same controller family, the MAX774 and MAX775 share the same basic function and pinout for negative buck-boost and positive boost, respectively. The MAX774EPA+ is the negative-output variant in the 8-PDIP package. No direct pin-compatible second source from another manufacturer is listed in the available records.
