L6902D013TR (Tape & Reel)  
rent error amplifier to have a constant voltage and con-  
stant current control.  
PROTECTION AGAINST FEEDBACK  
DISCONNECTION  
THERMAL SHUTDOWN  
By means of an on board current sense resistor and  
the availability of the current sense pins (both com-  
patible to Vcc and for Cs- compatible with GND too)  
a current limit programming is very simple and accu-  
rate (±5%). Moreover constant current control can be  
used to charge NiMH and NiCd batteries.

DISTRIBUTED POWER SUPPLY  
MOBILE PC & SUBNOTEBOOK  
The device can be used as a standard DC/DC con-  
verter with adjustable current limit (set by using the  
external sense resistor).  
■
■
The internal robust P-Channel DMOS transistor with a  
typical of 250m assures high efficiency and a mini-  
mum dropout even at high output current level. The in-  
ternal limiting current (latched function) of typical value  
of 2.5A protects the device from accidental output short  
circuit avoiding dangerous loads damage.

DESCRIPTION  
If the temperature of the chip goes higher than a fixed  
internal threshold (150°C with 20°C hysteresis), the  
power stage is turned off.  
The L6902D is a complete and simple step down  
switching regulator with adjustable current limit.  
Based on a voltage mode structure it integrates a cur-
