FEATURES  
DESCRIPTIO  
The LT®1930 and LT1930A are the industry’s highest  
power SOT-23 switching regulators. Both include an  
internal1A,36Vswitchallowinghighcurrentoutputstobe  
generated in a small footprint. The LT1930 switches at  
1.2MHz, allowing the use of tiny, low cost and low height  
capacitors and inductors. The faster LT1930A switches at  
2.2MHz, enabling further reductions in inductor size.  
Complete regulator solutions approaching one tenth of a  
square inch in area are achievable with these devices.  
Multiple output power supplies can now use a separate  
regulator for each output voltage, replacing cumbersome  
quasi-regulated approaches using a single regulator and  
custom transformers.

U
APPLICATIO S  
Aconstantfrequencyinternallycompensatedcurrentmode  
PWM architecture results in low, predictable output noise  
that is easy to filter. Low ESR ceramic capacitors can be  
used at the output, further reducing noise to the millivolt  
level. The high voltage switch on the LT1930/LT1930A is  
rated at 36V, making the device ideal for boost converters  
up to 34V as well as for single-ended primary inductance  
converter (SEPIC) and flyback designs. The LT1930 can  
generate 5V at up to 480mA from a 3.3V supply or 5V at  
300mA from four alkaline cells in a SEPIC design.
