LM2694 30V, 600 mA Step Down Switching Regulator

Check for Samples: LM2694

FEATURES

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

•

Integrated N-Channel Buck Switch

Integrated Start-Up Regulator

Input Voltage Range: 8V to 30V

No Loop Compensation Required

Ultra-Fast Transient Response

thermally enhanced WSON-10 package and

TSSOP-14 package. The feedback 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 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 features include: VCC under-

voltage lockout, thermal shutdown, gate drive under-

voltage lockout, and maximum duty cycle limiter.

Operating Frequency Remains Constant with

Load Current and Input Voltage Variations

Maximum Duty Cycle Limited During Start-Up

Adjustable Output Voltage

Valley Current Limit At 0.6A

Maximum Switching Frequency: 1 MHz
