LM5015  
High Voltage Monolithic Two-Switch Forward DC-DC  
Regulator  
General Description  
Features  
The LM5015 high voltage switch mode regulator features all  
the functions necessary to implement efficient high voltage  
Two-Switch Forward and Two-Switch Flyback regulators, us-  
ing a minimum of external components. This easy to use  
regulator integrates high side and low side 75 Volt N-Channel  
MOSFETs with a minimum 1 Amp peak current limit. The  
voltage across the MOSFETs employed in the two-switch  
topology is clamped to the input voltage, allowing the input  
voltage range to approach the rating of the MOSFETs. The  
regulator control method is based on current mode control  
providing inherent ease of loop compensation and line feed-  
forward for superior rejection of input transients.

Ultra-wide input voltage range: 4.25V to 75V  
Integrated high voltage bias regulator  
Adjustable output voltage  
1.5% feedback reference accuracy  
Current mode control with selectable compensation  
Wide bandwidth error amplifier  
Integrated current sensing and limiting  
50% maximum duty cycle limit  
Single resistor oscillator programming  
The operating frequency is set with a single resistor and is  
programmable up to 750 kHz. The oscillator can also be syn-  
chronized to an external clock. Additional protection features  
include cycle-by-cycle current limiting, thermal shutdown, un-  
der-voltage lockout and remote shutdown capability. The de-  
vice is available in the TSSOP-14EP package featuring an  
exposed die attach pad to enhance thermal dissipation.  
Oscillator synchronization capability  
Programmable soft-start  
Enable / Under-voltage Lockout (UVLO) pin  
Thermal shutdown
