Low-Cost, Internal-Switch, Step-Down
Regulator for LCD Displays
General Description
The MAX8723 is a high-efficiency, switch-mode, step-
down regulator with a 14V internal power switch. With
only a few external passive components, this low-cost
regulator can generate a fixed 3.3V or adjustable DC
output voltage of 2.0V to 3.6V of 2.0V to 3.6V (dual
mode) from a 6V to 13.2V DC source. The 13.2V input
voltage range makes this part ideal for LCD displays,
point-of-load regulators, and other 8/12V-powered
industrial equipment applications.
The MAX8723 can deliver up to 2A. It features an inter-
nal power MOSFET, a built-in bootstrap diode for its
MOSFET driver, and an interface for an external syn-
chronous rectifier MOSFET drive to replace the

? 6V to 13.2V Input Supply Range
? Integrated 14V 2A n-Channel MOSFET Switch
? Preset 1.5% Accurate 3.3V Fixed Output Voltage
or 2.0V to 3.6V Adjustable Output (Dual Mode)
? Current-Mode PWM Operation
? Frequency-Selectable 500kHz/1MHz/1.5MHz
? Internal 5V Linear Regulator Supports Up to 25mA

Schottky diode and improve efficiency. Its fixed-fre-
quency PWM/skip-mode operation and current-mode
control architecture provide fast load-transient
response without compensation. The switching fre-
quency is a pin-selectable 500kHz, 1MHz, or 1.5MHz,
minimizing the size of external components.
The MAX8723 has built-in soft-start, current-limit, ther-
mal-shutdown, and timer-delayed output-fault shutdown
functions. The soft-start function limits inrush current
during startup, avoiding transients that can trigger

The MAX8723 also includes a linear regulator (VL),
which provides a fixed 5V output (25mA) to support
small external loads. The reference output is high-pre-
cision (2V ± 1%) and can also supply small external
load currents.
The MAX8723 is available in the 16-pin 4mm x 4mm
