1.5 V/22 A Typical Characteristics
PMH 4518T
Start-up
Shut-down
Start-up enabled by connecting V
I at:
Tref = +25°C, IO = 22 A resistive load,
VI = 3.3 V.
Top trace: output voltage (0.5 V/div.).
Bottom trace: input voltage (2 V/div.).
Time scale: 10 ms/div..
Shut-down enabled by disconnecting V
I at:
Tref = +25°C, IO = 22 A resistive load,
VI = 3.3 V.
Top trace: output voltage (1.0 V/div.). Bottom
trace: input voltage (2 V/div.).
Time scale: 5.0 ms/div..
Output Ripple & Noise
Output Load Transient Response
Output voltage ripple (20mV/div.) at:
Tref = +25°C, IO = 22 A resistive load,
VI = 3.3 V. Time scale: 2 s/div.
See the filter in the Output ripple and noise
section (EMC Specification).
Output voltage response to load current step-
change (11-22-11 A) at:
Tref =+25°C, VI = 3.3 V.
Top trace: output voltage (50mV/div.).
Bottom trace: load current (10 A/div.).
Time scale: 0.1 ms/div..
