ISL1902
Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to the Block Diagram on page 4 and
Typical Application schematics starting on page 5. V_DD = 17V, R_RAMP = 54kΩ, C_RAMP = 470pF, T_A = -40°C to +125°C, Typical values are at T_A = +25°C.
Boldface limits apply over the operating temperature range, -40°C to +125°C. (Continued)
