(1)
The maximum output current is 3 amps or a maximum output power of 45 W, whichever is less. See the Application Information section
for further guidance.
(2)
For output voltages less than 19 V, the minimum input voltage is 15 V or (VO + 3) V, whichever is greater. For output voltages of 19 V
and higher, the minimum input voltage is (VO + 4) V. See the Application Information for further guidance.
(3)
The set-point voltage tolerance is affected by the tolerance and stability of RSET. The stated limit is unconditionally met if RSET has a
tolerance of 1% with 100 ppm/
°C or better temperature stability.
(4)
This control pin has an internal pullup, and if left open-circuit, the module operates when input power is applied. The open-circuit voltage
is typically 1.5 V. A small, low-leakage (< 100 nA) MOSFET is recommended for control. See the Application Information section for
further guidance.
(5)
Three external 4.7-F ceramic capacitors are required across the input (VI and GND) for proper operation. Locate the capacitor close to
the module.
(6)
100 F of output capacitance is required for proper operation. See the Application Information section for further guidance.
(7)
This is the typical ESR for all the electrolytic (nonceramic) capacitance. Use 17 m
as the minimum when using max-ESR values to
calculate.
