Description

The CPC1590 is a MOSFET Gate Driver that requires

no external power supply: it regulates the MOSFET

voltage, up to 200V, down to 12.2V for internal use. It

is specifically designed for low duty cycle switching

frequencies that drive 4nF of gate capacitance.

The CPC1590 accomplishes very fast MOSFET

turn-on by supplying stored charge, from an external

capacitor, to the MOSFET gate when input control

current is applied to the device’s LED. After the

MOSFET is turned on, photocurrent from the input

optocoupler keeps it on for as long as sufficient input

control current flows, so there is no low-frequency

operating limit. When the MOSFET is turned off, the

storage capacitor charges from the device’s regulated

internal voltage in preparation for the next turn-on.

Because it is provided in a small, 8-pin, Flatpack

package and requires no separate power supply, the

CPC1590 provides a flexible design solution that

consumes the least amount of PCB land area.
