2-CHANNEL SWITCHING REGULATOR

FEATURES

GENERAL DESCRIPTION

The AAT1343 provides an integrated two-channel

pulse-width-modulation (PWM) solution for the

power supply of DC-DC system; this device offers

z Complete PWM Power Control Circuitry

z Precision Reference：2.5V ± 1% (25 ^oC)

z Under-Voltage Lockout (UVLO) Protection

z Open Drain Output

the systems engineer flexibility to tailor-make the

power supply circuitry for specific applications.

Each channel contains its own error amplifier,

PWM comparator, dead–time control (DTC) and

output driver. The under-voltage protection,

oscillator, short circuit protection and voltage

reference circuit are the common features for these

two channels.

z Output Short Circuit Protection

z Low Dissipation Current：1.6mA

z Dead-Time Control：0 % to 100%

z Wide Operating Frequency：

10kHz to 800kHz

V_DDRange：4.0V to 14.0V

Both channels of AAT1343 can be used for DC-DC

converter operations including step-up, step-down,

and inverting. Dead-time control can be set to

provide 0% to 100% dead-time through a resistive

divider network. Soft-start can be implemented by

paralleling the DTC resistor with a capacitor. Two

dead-time control inputs are assigned for channel 1

(CH1) and channel 2 (CH2) individually, and

dead-time control inputs can be used to control on /

off operation.
