XL6008

400KHz 60V 3A Switching Current Boost / Buck-Boost / Inverting DC/DC Converter

Features

General Description

n Wide 3.6V to 32V Input Voltage Range

n Positive or Negative Output Voltage

Programming with a Single Feedback Pin

n Current Mode Control Provides Excellent

Transient Response

The XL6008 regulator is a wide input range,

current mode, DC/DC converter which is

capable of generating either positive or

negative output voltages. It can be configured

as either a boost, flyback, SEPIC or inverting

converter. The XL6008 built in N-channel

power MOSFET and fixed frequency

oscillator, current-mode architecture results in

stable operation over a wide range of supply

and output voltages.

n 1.25V reference adjustable version

n Fixed 400KHz Switching Frequency

n Maximum 3A Switching Current

n SW PIN Built in Over Voltage Protection

n Excellent line and load regulation

n EN PIN TTL shutdown capability

n Internal Optimize Power MOSFET

The XL6008 regulator is special design for

portable electronic equipment.

High efficiency up to 92%

Pin Number

Pin Name Description

GND

Ground Pin.

Enable Pin. Drive EN pin low to turn off the device, drive it

high to turn it on. Floating is default high.

Power Switch Output Pin (SW).

Supply Voltage Input Pin. XL6008 operates from a 3.6V to

32V DC voltage. Bypass Vin to GND with a suitably large

capacitor to eliminate noise on the input.

VIN

Feedback Pin (FB). The feedback threshold voltage is 1.25V.
