DESCRIPTION
The LX3005 is a 420kHz fixed
frequency PWM buck (step-down) DC-DC
converter, capable of driving a 2A load
with high efficiency, low ripple and
excellent line and load regulation. The
device operates over a wide input voltage
range of 4.75V to 25V, and the output
voltage can be externally set from 0.8V to
a voltage near VIN, as the PWM control
circuit is able to adjust the duty ratio
linearly from 0% to close to 100%.
The LX3005 device integrates a
high-side low RDS
ON
PMOS for a low
cost and high efficiency solution. An
internal transconductance error amplifier
is used in the control loop allowing
flexibility to compensate the system using
an all ceramic capacitor system.
The LX3005 also features an enable
function, internal circuitry for soft start,
and protection schemes such as thermal
shutdown, over-current protection, and
short-circuit protection. When OCP or
SCP is triggered, the device operating
frequency will be reduced from typically
420kHz to typically 40kHz, limiting the
output power capability.
The LX3005 serves as an ideal power
supply device for portable devices,
especially for chipset power in portable
systems. It’s widely used for PDVD, LCD
monitor and DPF chipset power sources.
The LX3005 is available in SOIC8
package and is functional from an ambient
temperature range of 0˚C to 85˚C.
