AT1396A/B/C/D
Preliminary Product Information
6-Channel DC-DC Converter for DSC
Features
• 95% Efficient possible DC/DC Converter
• Combine Step-Up and Step-Down for
90% Efficient Boost-Buck
• Bulit-in LED Driver and Open LED
Overvoltage Protection
• Transformerless Inverting Controller for CCD
Bias
• 2 Channel Built-in MOSFET Current- Mode
PWM and 4 Channel Extra PWM Controllers
(CH-3 Synchronous Output)
• Up to 1MHz Operating Frequency
• Shutdown Current <1uA
• Built-in Soft-Start Function
• Built-in Short-Circuit Protection Function
• QFN48 Package
General Description
The AT1396A/B/C/D provide a complete power
supply solution for digital cameras. They improve
performance, component count, and size compared
to other multi-channel controllers in 2-cell AA,
1-cell Li-Ion, and dual-battery designs. On-chip
MOSFETs provide up to 92~95% efficiency for
critical power supplies, while additional channels
operate with external FETs for optimum design
flexibility. All channels DC/DC operate at one
fixed frequency settable from 100KHz to 1MHz to
optimize size, cost, and efficiency.
