MCP16301

DC CHARACTERISTICS (CONTINUED)

Electrical Characteristics: Unless otherwise indicated, TA = +25°C, VIN = VEN = 12V, VBOOST - VSW = 3.3V,

VOUT = 3.3V, IOUT = 100 mA, L = 15 µH, COUT = CIN = 2 X 10 µF X7R Ceramic Capacitors

Boldface specifications apply over the TA range of -40oC to +85oC.

Note 1: The input voltage should be > output voltage + headroom voltage; higher load currents increase the input voltage

necessary for regulation. See characterization graphs for typical input to output operating voltage range.

2: For VIN < VOUT, VOUT will not remain in regulation.

3: VBOOST supply is derived from VOUT.
