SNVS413A –JANUARY 2006–REVISED APRIL 2013

LM2695 High Voltage (30V, 1.25A) Step Down Switching Regulator

Check for Samples: LM2695

FEATURES

DESCRIPTION

The LM2695 Step Down Switching Regulator features

all of the functions needed to implement a low cost,

efficient, buck bias regulator capable of supplying

1.25A to the load. This buck regulator contains a 33V

N-Channel Buck Switch, and is available in the

thermally enhanced WSON-10 and HTSSOP-14

packages. The hysteretic regulation scheme requires

no loop compensation, results in fast load transient

response, and simplifies circuit implementation. The

operating frequency remains constant with line and

load variations due to the inverse relationship

between the input voltage and the on-time. The

current limit detection is set at 1.25A. Additional

features include: VCC under-voltage lockout, thermal

shutdown, gate drive under-voltage lockout, and

maximum duty cycle limiter.
