GENERAL DESCRIPTION

The ADP1829 is a versatile, dual, interleaved, synchronous

PWM buck controller that generates two independent output

rails from an input of 3.0 V to 18 V, with power input voltage

ranging from 1.0 V to 24 V. Each controller can be configured

to provide output voltages from 0.6 V to 85% of the input

voltage and is sized to handle large MOSFETs for point-of-load

regulators. The two channels operate 180° out of phase,

reducing stress on the input capacitor and allowing smaller, low

cost components. The ADP1829 is ideal for a wide range of

high power applications, such as DSP and processor core I/O

power, and general-purpose power in telecommunications,

medical imaging, PC, gaming, and industrial applications.

frequencies between 300 kHz and 1 MHz. The ADP1829

includes soft start protection to prevent inrush current from the

input supply during startup, reverse current protection during

soft start for precharged outputs, as well as a unique adjustable

lossless current-limit scheme utilizing external MOSFET sensing.

For applications requiring power supply sequencing, the

ADP1829 also provides tracking inputs that allow the output

voltages to track during startup, shutdown, and faults. This

feature can also be used to implement DDR memory bus

termination.

The ADP1829 is specified over the −40°C to +125°C junction

temperature range and is available in a 32-lead LFCSP package.

The ADP1829 operates at a pin-selectable, fixed switching

frequency of either 300 kHz or 600 kHz, minimizing external

component size and cost. For noise-sensitive applications, it can

also be synchronized to an external clock to achieve switching
