AT1396A/B/C/D
Preliminary Product Information
6-Channel DC-DC Converter for DSC
Figure 6. +15V and –7.5V CCD Bias with Charge-Pump (using AT1202 to regulated the negative output)
Soft-Start Setting (CH1~CH6)
The AT1396 all channels feature a soft-start function that limits inrush current and
prevents excessive battery loading at start-up by ramping the output voltage of each
channel up to the regulation voltage. Consider the input voltage and load current to
design the capacitor connected to the SS pin. It can calculate the CH1~6 soft start
time Ts(s)(valid threshold 0.3~0.8V interval).
