DESCRIPTION

FEATURES

The SC1405 is a Dual-MOSFET Driver with an internal

Overlap Protection Circuit to prevent shoot-through

from V_INto GND in the main switching and syn-

chronous MOSFET’s. Each driver is capable of driving

a 3000pF load in 20ns rise/fall time and has ULTRA-

FAST propagation delay from input transition to the

gate of the power FET’s. The Overlap Protection circuit

ensures that the second FET does not turn on until the

top FET source has reached a voltage low enough to

prevent shoot-through. The delay between the bottom

gate going low to the top gate transitioning to high is

externally programmable via a capacitor for optimal

reduction of switching losses at the operating fre-

quency. The bottom FET may be disabled at light loads

by keeping S_MOD low to trigger asynchronous opera-

tion, thus saving the bottom FET’s gate drive current

and inductor ripple current. An internal voltage refer-

ence allows threshold adjustment for an Output Over-

Voltage protection circuitry, independent of the PWM

feedback loop. Under-Voltage-Lock-Out circuit is in-

cluded to guarantee that both driver outputs are low

when the 5V logic level is less than or equal to 4.4V

(typ) at supply ramp up (4.35V at supply ramp down). A

CMOS output provides status indication of the 5V sup-

ply. A low enable input places the IC in stand-by mode

thereby reducing supply current to less than 10µA.

SC1405 is offered in a high pitch (.025” lead spacing)

TSSOP package.

•= ^{Fast rise and fall times (20ns typical with 3000pf}

load)

•= 20ns max. Propagation delay (BG going low)

•= Adaptive/programmable shoot-through protection

•= Wide input voltage range (4.5-25V)

•= Programmable delay between MOSFET’s

•= Power saving asynchronous mode control

•= Output overvoltage protection/overtemp shutdown

•= Under-Voltage lock-out and power ready signal

•= Less than 10µA stand-by current (EN=low)

•= Power ready output signal

APPLICATIONS

•= ^{High Density/Fast transient power supplies}

•= Motor Drives/Class-D amps

•= High frequency (to 1.2 MHz) operation allows use

of small inductors and low cost caps in place of

electrolytics

•= Portable computers
