ISL78268規(guī)格書詳情

The ISL78268 is a grade 1, automotive, synchronous buck

controller with integrated high/low side MOSFET drivers. It

supports a wide operating input voltage range of 5V to 55V

and up to 60V at VIN when not switching. The integrated driver

offers adaptive dead-time control and is capable of supplying

up to 2A sourcing and 3A sinking current, allowing the

ISL78268 to support power stages designed for a wide range

of loads, from under 1A to over 25A.

ISL78268’s fully synchronous architecture enables power

conversion with very high efficiency and improved thermal

performance over standard buck converters. The ISL78268 also

offers diode emulation mode for improved light load efficiency.

While ISL78268 is a peak current mode PWM controller, it

also includes a dedicated average output current modulation

loop, which achieves constant output current limiting for

applications such as battery charging, super-cap charging, and

temperature control systems where a constant current must

be provided.

The ISL78268 supports switching frequencies from 50kHz to

1.1MHz allowing the user the flexibility to trade-off switching

frequency and efficiency against the size of external

components.

The ISL78268 offers comprehensive protection features. It

includes robust current protection with cycle-by-cycle peak

current limiting, average current limiting, and a selectable

hiccup or latch-off fault responses. In addition, it offers

protection against over-temperature, as well as input and

output overvoltages.
