Graham Prophet @ eedesignnewseurope.com discuss about the new Linear’s step-down inductor-less controller. LTC7820 is, a high power fixed ratio charge pump DC/DC controller that eliminates the power inductor in a non-isolated intermediate bus converter, allowing up to a 50% reduction in circuit size and up to 4000 W/in³ power density. The 72V fixed-ratio DC/DC controller […]
LTC7820 – Fixed Ratio High Power Inductorless (Charge Pump) DC/DC Controller
https://www.electronics-lab.com/ltc7820-fixed-ratio-high-power-inductorless-charge-pump-dcdc-controller/
The LTC7820 is a fixed ratio high voltage high power switched capacitor/charge pump controller. The device includes four N-channel MOSFET gate drivers to drive external power MOSFETs in voltage divider, doubler or inverter configurations. The device achieves a 2:1 stepdown ratio from an input voltage as high as 72V, a 1:2 step-up ratio from an […]
