LTC1436-PLL
Electromagnetic interference (EMI) is a potential problem for the circuit designer. Switching regulators can cause EMI in many products. Linear Technology has developed new techniques like spread-spectrum modulation, phase-locked synchronization and Adaptive Power mode that can reduce the amount of unwanted interference.
New IC solves old problems
The LTC1436-PLL is a constant frequency, current mode, synchronous step-down switching regulator that controls external N-channel MOSFETs ...
