AT1396B Datasheet | Aimtron Technology

Features - 95% Efficient possible DC/DC Converter - bine 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 <1u A - Built-in Soft-Start Function - Built-in Short-Circuit Protection Function - QFN48 Package General Description The AT1396A/B/C/D provide a plete power supply solution for digital cameras. They improve performance, ponent count, and size pared 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.
