High-voltage step-up DC-DC regulator integrates a 36 V, 400 mΩ NMOS switch for compact boost, SEPIC, Cuk, or flyback supplies. The device operates from 2.4 V to 5.5 V inputs and supports adjustable outputs up to 32 V. It uses fixed-frequency 500 kHz PWM operation with skip mode, internal compensation, soft start, cycle-by-cycle current limiting, and output overvoltage protection. Shutdown current is typically 300 nA, and the operating junction temperature range is -40°C to +125°C.
