aat1155iks-2.5-t1 Advanced Analogic Technologies, Inc., aat1155iks-2.5-t1 Datasheet - Page 15

• Manufacturer Part Number: aat1155iks-2.5-t1
• Description: Aat1155 | 1mhz 2.5a Step-down Dc/dc Converter
• Manufacturer: Advanced Analogic Technologies, Inc.

Adjustable Output
For applications requiring an output other than the
fixed outputs available, the 1V version can be pro-
grammed externally. Resistors R3 and R4 of
Figure 1 force the output to regulate higher than

1 volt. For accurate results (less than 1% error for
all outputs), select R4 to be 10kΩ. Once R4 has
been selected, R3 can be calculated. For a 1.25
volt output with R4 set to 10kΩ, R3 is 2.5kΩ.
