ISL62391 Datasheet, PDF (4/20 Pages) Intersil Corporation – High-Efficiency, Triple-Output System Power Supply Controller for Notebook Computers

ISL62391, ISL62392
Electrical Specifications
Circuit of Figure 1 and Figure 2, LDO3, OUT1, OUT2, and REF, VIN = 12V, EN = VCC, T_A = -40°C to +100°C,
unless otherwise noted. Typical values are at T_A = +25°C. Parameters with MIN and/or MAX limits are 100%
tested at +25°C, unless otherwise specified. Temperature limits established by characterization and are not
production tested. (Continued)

NOTES:
3. Limits established by characterization and are not production tested.
4. F_SW accuracy reflects IC tolerance only; it does not include frequency variation due to V_IN, V_OUT, L_OUT, ESR_COUT, or other application specific
parameters.
