LM2694

30V, 600 mA Step Down Switching Regulator

n No loop compensation required

n Ultra-Fast transient response

n Operating frequency remains constant with load current

and input voltage variations

n Maximum Duty Cycle Limited During Start-Up

n Adjustable output voltage

n Valley Current Limit At 0.6A

n Maximum switching frequency: 1 MHz

n Precision internal reference

n Low bias current

n Highly efficient operation

General Description

The LM2694 Step Down Switching Regulator features all of

the functions needed to implement a low cost, efficient, buck

bias regulator capable of supplying 0.6A to the load. This

buck regulator contains an N-Channel Buck Switch, and is

available in the 3 x 3 thermally enhanced LLP-10 package

and a TSSOP-14 package. The feedback regulation scheme

requires no loop compensation, results in fast load transient

response, and simplifies circuit implementation. The operat-

ing frequency remains constant with line and load variations

due to the inverse relationship between the input voltage and

the on-time. The valley current limit results in a smooth

transition from constant voltage to constant current mode

when current limit is detected, reducing the frequency and

output voltage, without the use of foldback. Additional fea-

tures include: VCC under-voltage lockout, thermal shut-

down, gate drive under-voltage lockout, and maximum duty

cycle limiter.

n Thermal shutdown

Typical Applications

n High Efficiency Point-Of-Load (POL) Regulator

n Non-Isolated Telecommunication Buck Regulator

n Secondary High Voltage Post Regulator
