A8698
Wide Input Voltage 3.0 A Step Down Regulator
Features and Benefits
Description

?
?
8 to 25 V input range
Integrated DMOS switch
Adjustable fixed off-time
Highly efficient
Adjustable 0.8 to 20 V output
The A8698 is a constant off-time current mode step-down
regulator with a wide input voltage range. Regulation voltage is
set by external resistors, to output voltages as low as 0.8 V.
The A8698 includes an integrated power DMOS switch to
reduce the total solution footprint. It also features internal
compensation, allowing users to design stable regulators with
minimal design efforts.
The off-time can be set with an external resistor, allowing
flexibility in inductor selection. Additionally, the A8698 has
a logic level enable pin which can shut the device down and
put it into a low quiescent current mode for power sensitive
applications.
Package: 8-Lead SOIC with exposed
The A8698 is supplied in a low-profile 8-lead SOIC with
exposed pad (package LJ). Applications include:
thermal pad (suffix LJ)
