VSSOP - 10

DESCRIPTION

The LM5006 Step Down Switching Regulator features

all of the functions needed to implement a low cost,

efficient Buck bias regulator. This high voltage

regulator contains an 80V N-Channel MOSFET

Switch and a startup regulator. The device is easy to

implement and is provided in an VSSOP-10 package.

The regulator’s control scheme uses an on-time

inversely proportional to V_IN. This feature results in

the operating frequency remaining relatively constant

with line and load variations. The control scheme

requires no loop compensation, resulting in fast

transient response. An intelligent current limit is

implemented with a forced off-time which is inversely

proportional to V_OUT. This scheme ensures short

circuit control while providing minimum foldback.

Other features include: Thermal Shutdown, VCC

Under Voltage Lock-out, Max Duty Cycle Limiter, a

Pre-charge Switch, a programmable Under Voltage

Detector with a status flag output, and a gate driver

output for a synchronous rectifier.
