LTC7820EUFD#PBF Product Details
The LTC7820EUFD#PBF 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 step-down ratio from an input voltage as high as 72V, a 1:2 step-up ratio from an input voltage as high as 36V, or a 1:1 inverting ratio from an input voltage up to 36V. Each power MOSFET is switched with 50% duty cycle at a constant pre-programmed switching frequency. System efficiency can be optimized to over 99%. The LTC7820EUFD#PBF provides a small and cost effective solution for high power, non-isolated intermediate bus applications with fault protection.
The LTC7820EUFD#PBF switching frequency can be linearly programmed from 100 kHz to 1MHz. The device is available in a thermally enhanced 28-lead QFN package with some no-connect pins for high voltage compatible pin spacing.
