Preliminary
VP3682
Boost/SEPIC DC/DC Controller with I2C Bus
General Description
Features
The VP3682 is a versatile controller designed for use in Boost and SEPIC power regulator and topologies that needs an external low-side NMOSFET acting as primary switch. Besides cycleby-cycle current limiting, current mode control scheme also makes it wide bandwidth and good transient response. The current limit can be programmed simply with an external resistor.
The switching frequency can be set in any value between 100kHz and 1MHz with a resistor or any external clock source. The VP3682 can be operated at high switching frequency to save the solution board size.
