Portable Electronic Equipment General Description

The XL6010 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 XL6010 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.

The XL6010 regulator is special design for portable electronic equipment applications.

Table 1 Pin Description

Pin Number Pin Name Description

1 GND Ground Pin.

2 EN

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

high to turn it on. Floating is default high.

3 SW Power Switch Output Pin (SW).

4 VIN Supply V oltage Input Pin. XL6010 operates from a 5V to 32V

DC voltage. Bypass Vin to GND with a suitably large

capacitor to eliminate noise on the input.

5 FB Feedback Pin (FB). Through an external resistor divider

network, FB senses the output voltage and regulates it. The

feedback threshold voltage is 1.25V .
