ADP1829ACPZ-R7

ADP1829 is a versatile, dual, interleaved, synchronous PWM buck controller that generates two independent output rails from an input of 3V to 20V, with power input voltage ranging from 1V to 24V. Each controller can be configured to provide output voltages from 0.6V 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. It 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. It is used in application such as telecommunications and networking systems, medical imaging systems, base station power, set-top boxes, printers, DDR termination etc.

• Supply input range is 3V to 20V
• Wide power stage input range is 1V to 24V
• Interleaved operation results in smaller, low cost input capacitor
• Soft start, thermal overload, current-limit protection
• Internal linear regulator, lossless RDSON current-limit sensing
• Reverse current protection during soft start for handling precharged outputs
• Independent Power OK outputs, voltage tracking for sequencing or DDR termination
• Quiescent current is 1.5mA typical, shutdown current is 10μA typical
• Oscillator frequency is 300KHz typical at (SYNC = FREQ = GND, fSW = fOSC)
• Operating temperature is -40°C to +85°C, package style is 32-lead LFCSP
