DESCRIPTION

The LM25007 is a monolithic step-down switching

regulator featuring all of the functions needed to

implement a low cost, efficient, power supply.

Capable of driving a 0.5A load over a 9V-42V input

voltage range, this device is easy to apply and is

provided in the small VSSOP-8 and the thermally enhanced WSON-8 packages. Ultra-fast transient

response is achieved through the use of a constant

on-time architecture with Vin feed forward. This

feature provides an almost constant operating

frequency over load and input voltage variations. The

operating frequency can be adjusted with a single

resistor. This architecture is easy to use and tolerant

of component selection. An intelligent current limit is

implemented in the LM25007 with forced off time that

is inversely proportional to Vout thus ensuring recovery from fault conditions. The output voltage

may be set from 2.5V to >30V. To improve efficiency

in light load applications, the Vcc pin can be

connected to an external voltage source to eliminate

the drop through the internal regulator. Additional

features include: thermal shutdown, Vcc under-

voltage lockout, gate drive under-voltage lockout, and

max duty cycle limiter.
