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 inherent 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 necessary in high input voltage applications. The operating frequency 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. Additional 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.
