The LM5001 High Voltage Switching Mode Regulator features efficient high voltage boost, flyback, SEPIC and transponder with few external components. This easy-to-use regulator integrates a 1 amp peak current limit of 75 volts N-channel MOSFET. Current mode control provides inherently simple loop compensation and superior input transient suppression line voltage feedforward. Its switching frequency is set to one resistor and programmable up to 1.5MHz. The oscillator can also be synchronized to an external clock. Other protection features include: current limiting, thermal shutdown, undervoltage lockout, and remote shutdown function. The device is available in two SO-8 and LLP-8 packages.
