The point of load (POL) integrated voltage regulator can operate directly from 12V at high switching frequency without the need for a heatsink or fan.
It also features remote differential sensing, enabling 0.5% Vref accuracy between 0 and 105°C, making it well suited for high power fpgas and asics requiring 1% dc or 3% dc and ac accurate power supply.
In addition, the IR3846 features a proprietary modulator scheme that enables jitter free and noise free operation to allow higher frequency/higher bandwidth operation for better transient response and fewer output capacitors, as well as pcb space savings of up to 20%.
The device's pinout is optimised for easy placement of bypass capacitors and the internal thermally compensated current limit offers three settings that allow programmability without extra components and layout complications.
