Микросхемы и комплектующие DC/DC контроллер LT8310MPFE#PBF

The LT8310MPFE#PBF is a resonant reset Forward Converter Controller drives the gate of a low side N-channel MOSFET from an internally regulated 10V supply. It features duty mode control that generates a stable, regulated, isolated output using a single power transformer. With the addition of output voltage feedback, via opto-coupler (isolated) or directly wired (non-isolated), current-mode regulation is activated, improving output accuracy and load response. The flexibility to choose transformer turns ratio makes high step-down or step-up ratios possible without operating at duty cycle extremes. The user can program the switching frequency from 100 to 500kHz to optimize efficiency, performance or external component size. A synchronous output is available for controlling secondary side synchronous rectification to improve efficiency. User programmable protection features include monitors on input voltage (UVLO and OVLO) and switch current (overcurrent limit).

• Duty mode control regulates an isolated output without an opto
• High efficiency synchronous control
• Short-circuit (Hiccup Mode) overcurrent protection
• Programmable OVLO and UVLO with hysteresis
• Synchronizable to an external clock
• Positive or negative polarity output voltage feedback with a single FBX pin
• Programmable soft-start
