L6997STR - Brand New STMicroelectronics DC DC Switching Controllers
-
Description
The device is a high efficient solution for networking dc/dc modules and mobile applications compatible with 3.3V bus and 5V bus.
Its able to regulate an output voltage as low as 0.6V. The constant on time topology assures fast load transient response. The embedded voltage feed- forward provides nearly constant switching frequency operation in spite of a wide input voltage range. An integrator can be introduced in the control loop to reduce the static output voltage error.
The remote sensing improves the static and dynamic regulation, recovering the wires voltage drop.
Pulse skipping technique reduces power consump tion at light loads. Drivers current capability allows output currents in excess of 20A.Features
