.
(*1) Rating is conditional on the module being directly soldered to a 4-layer PCB with 1 oz. copper.
(*2) Up to 10 ms pulse period at 10 % maximum duty.
(*3) This control pin has an internal pull-up. If it is left open-circuit the module will operate when input power
is applied.
(*4) The external input capacitor must be rated at or above 500mA rms of ripple current.
(*5) The typical value of external output capacitance value ensures that VTT meets the specified transient
performance requirements for the memory bus.
Caution
The above electrical characteristics are guaranteed in the condition that the impedance of the input voltage
source is sufficiently low as shown in clause 10.
Connecting an input inductance or using an input power supply with output inductance may cause an unstable
operation of this product. Please check the proper operation of this product with the peripheral circuits on your
product.
9 .2 Safe Operating Area (SOA)
The above SOA represents the condition at which internal components are at or below the manufacturer’s
maximum operating temperatures. Derating limits apply to modules soldered directly to 4 in.×4in. 4 layer PCB
with 1 oz. copper. For more reliable operation, appropriate derating is desirable.
