ISL78263规格书详情
描述 Description
The ISL78263 offers synchronous boost and buck controllers. The boost controller operates either as an independent channel or as a pre-boost function that supplies the buck controller. The low-IQ buck controller uses only 6µA quiescent current, allowing it to support low-power, always-on operation. Both controllers support wide duty-cycles for switching frequencies from 200kHz to 2.2MHz. Both devices can be synchronized to an external clock and offer programmable spread spectrum clocking to mitigate EMI.
In pre-boost buck mode, the boost of the ISL78263 can be set to activate during falling VIN transients and continues to operate with an input voltage down to 2.1V. This allows the buck output to maintain regulation, even as the VIN voltage falls below its output. To support the increase in input current that occurs when VIN falls, the ISL78263 integrates robust MOSFET drivers to allow the use of multiple FETs in parallel.
ISL78263 is qualified to AEC-Q100 Grade 1 and is specified to operate across an ambient temperature range of -40°C to 125°C. The device is available in a 5mmx5mm, 32 Ld WFQFN (Wettable Flank) package. The features of the ISL78263 make it ideally suited as a front-end regulator for automotive systems that must maintain always-on operation and support severe cold-cranking transients.
