AAT1343
2-CHANNEL SWITCHING REGULATOR
FEATURES
GENERAL DESCRIPTION
z Complete PWM Power Control Circuitry
The AAT1343 provides an integrated two-channel
z Precision Reference 2.5V ± 1% (25 oC)
z Under-Voltage Lockout (UVLO) Protection
z Open Drain Output
z Output Short Circuit Protection
z Low Dissipation Current 1.6mA
z Dead-Time Control 0 % to 100%
pulse-width-modulation (PWM) solution for the
power supply of DC-DC system; this device offers
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,
z Wide Operating Frequency
10kHz to 800kHz
z VDD Range 4.0V to 14.0V
oscillator, short circuit protection and voltage
reference circuit are the common features for these
two channels.
