NOTES:

3. FSW accuracy reflects IC tolerance only; it does not include frequency variation due to VIN, VOUT, LOUT, ESRCOUT, or other application specific

parameters.

4. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.

Electrical Specifications

VIN = 12V, EN = VCC, TA = -40°C to +100°C, unless otherwise noted. Typical values are at TA = +25°C.

Boldface limits apply over the operating temperature range. (Continued)
