5% Output Voltage Accuracy • Current Mode Control with Selectable Compensation • Wide Bandwidth Error Amplifier • Integrated Current Sensing and Limiting • Integrated Slope Compensation • 85% Maximum Duty Cycle Limit • Single Resistor Oscillator Programming • Oscillator Synchronization Capability • Enable / Undervoltage Lockout (UVLO) Pin • Thermal Shutdown 2 Applications • DC-DC Power Supplies for Industrial, Communications, and Automotive Applications • Boost, Flyback, SEPIC and Forward Converter Topologies 3 Description The LM5001 high-voltage switch-mode regulator features all of the functions necessary to implement efficient high-voltage Boost, Flyback, SEPIC and Forward converters, using few external components.
This easy-to-use regulator integrates a 75-V NChannel MOSFET with a 1-A peak current limit.
Current mode control provides inherently simple loop compensation and line-voltage feed-forward for superior rejection of input transients.
The switching frequency is set with a single resistor and is programmable up to 1.
5 MHz.
The oscillator can also be synchronized to an external clock.
Additional protection features include: current limit, thermal shutdown, undervoltage lockout and remote shutdown capability.
