LM5005  
High Voltage 2.5 Amp Buck Regulator  
General Description  
Features  
The LM5005 high voltage switching regulator features all of  
the functions necessary to implement an efficient high voltage  
buck regulator using a minimum of external components. This  
easy to use regulator includes a 75V N-Channel buck switch  
with an output current capability of 2.5 Amps. The regulator  
control method is based upon current mode control utilizing  
an emulated current ramp. Current mode control provides in-  
herent line feed-forward, cycle-by-cycle current limiting and  
ease of loop compensation. The use of an emulated control  
ramp reduces noise sensitivity of the pulse-width modulation  
circuit, allowing reliable control of very small duty cycles nec-  
essary in high input voltage applications. The operating fre-  
quency is programmable from 50kHz to 500kHz. An oscillator  
synchronization pin allows multiple LM5005 regulators to self-  
synchronize or to be synchronized to an external clock. Ad-  
ditional protection features include: current limit, thermal  
shutdown and remote shutdown capability. The device is  
available in a power enhanced TSSOP-20 package featuring  
an exposed die attach pad to aid thermal dissipation.  
Integrated 75V, 2.5A N-Channel Buck Switch  
Ultra-wide input voltage range from 7V to 75V  
Internal high voltage bias regulator  
Adjustable output voltage from 1.225V  
1.5% feedback reference accuracy  
Current mode control with emulated inductor current ramp  
Single resistor oscillator frequency setting  
Oscillator synchronization input  
Programmable soft-start  
Shutdown / Standby input  
Wide bandwidth error amplifier  
Thermal Shutdown
