L5973D  
2.5A switch step down switching regulator  
General features  
2.5A Internal switch  
Operating input voltage from 4V to 36V  
3.3V / ( 2%) reference voltage  
Output voltage adjustable from 1.235V to 35V  
Low dropout operation: 100% duty cycle  
250KHz Internally fixed frequency  
Voltage feedforward  
HSOP8 Exposed Pad  
Description  
The L5973D is a step down monolithic power  
switching regulator with a minimum switch current  
limit of 2.5A so it is able to deliver more than 2A  
DC current to the load depending on the  
application conditions.  
The output voltage can be set from 1.235V to  
35V.  
The high current level is also achieved thanks to  
an SO8 package with exposed frame, that allows  
to reduce the Rth(j-amb) down to approximately  
40°C/W.  
The device uses an internal P-Channel D-MOS  
transistor (with a typical Rdson of 250mW) as  
switching element to minimize the size of the  
external components.  
An internal oscillator fixes the switching frequency  
at 250KHz.  
Having a minimum input voltage of 4V only, it is  
particularly suitable for 5V bus, available in all  
computer related applications.  
Zero load current operation  
Internal current limiting  
Inhibit for zero current consumption  
Synchronization  
Protection against feedback disconnection  
Thermal shutdown  
Applications  
Consumer: STB, DVD, TV, VCR, car radio,  
LCD monitors  
Networking: XDSL, modems, DC-DC modules  
Computer: printers, audio/graphic cards,  
optical storage, hard disk drive  
Industrial: changers, car battery, DC-DC  
converters  
Pulse by pulse current limit with the internal  
frequency modulation offers an effective constant  
current short circuit protection.
