DPA-Switch uses the same proven topology as TOPSwitch®,  
cost effectively integrating a power MOSFET, PWM control, fault  
protection and other control circuitry onto a single CMOS chip.  
High performance features are enabled with three user  
configurable pins. Hysteretic thermal shutdown is also provided.  
In addition, all critical parameters (i.e. current limit, frequency,  
PWM gain) have tight temperature and absolute tolerance, to  
simplify design and reduce system cost.  
Table 1. Output Power Table.  
Notes:  
1. Maximum output power is limited by device internal current limit.  
2. See Applications Considerations section for complete description of assumptions  
and for output powers with other input voltage ranges.  
3. For device dissipation of 1.5 W or below, use P or G packages. Device  
dissipation  
above 1.5 W is possible with R package.  
4. Packages: P: DIP-8, G: SMD-8, R: TO-263-7C. For lead-free package options,  
see Part Ordering Information.  
5. Available in R package only.  
6. Due to higher switching losses, the DPA425 may not deliver additional power  
compared to a smaller device.  
7. Available in P and G package only.  
8. DPA422 not recommended for new designs, use DPA423 instead.
