No external resistor divider. The 275 mA current limit is the total from that rail. ## Switcher basics — 160 kHz, no sync rectifier Switching frequency is 160 kHz. No synchronous rectifier, so the freewheeling diode drop eats into efficiency at higher currents or low input voltage. For a 275 mA load, expect the typical diode loss to be a few hundred milliwatts—acceptable for moderate thermal budgets in an SOIC-8. The 8-SOIC footprint is industry-standard, so layout guidelines from any buck-boost app note apply. Input decoupling close to the IC and a Schottky diode rated for at least the input voltage keep the switching loop tight. ## Lifecycle and sourcing reality Lifecycle status is Active. No EOL notice. ROHS3 compliant.","metaTitle":"MAX735CSA+ Buck-Boost Regulator, -5V Fixed Output, 275mA","metaDescription":"MAX735CSA+ is an active-production buck-boost regulator from Maxim Integrated.
