TB62763FMG Datasheet (Toshiba) - Step Up Type DC/DC Converter

TB62763FMG, Step Up Type DC/DC Converter

Switch terminal for DC/DC converter.

Nch MOSFET built-In.

Over voltage protection terminal.

IC switching operation is disabled when OVP terminal voltage is over 32.5 V (TYP.).

If the voltage returns to 31.5V (TYP) or less, operation is enabled again.

LED IF setting resistor connecting terminal.
