LTC7840 Boost Controllers

Analog Devices Inc. LTC7840 Boost Controllers are dual phase dual output and constant frequency current mode nonsynchronous controller with hiccup mode. These boost controllers operate from 5.5V to 60V input supply voltage range. The LTC7840 boost controllers can be configured for the SEPIC and flyback topologies. These controllers feature a precise 1.2V internal reference. The LTC7840 controllers include internal 10V LDO with under-voltage lockout protection for its on-chip gate driver. These boost controllers come in 28-lead thermally enhanced TSSOP package or 28-lead QFN package. Applications include an automotive system, telecom system, and industrial power supplies.
