Datasheet Analog Devices ADP1828

Synchronous Buck PWM,
Step-Down, DC-to-DC Controller
ADP1828 Data Sheet
FEATURES to regulate an output voltage as low as 0.6 V to 85% of the input
voltage and is sized to handle large MOSFETs for point-of-load
regulators. The ADP1828 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 operates from input
bias voltages of 3 V to 20 V with an internal LDO that generates
a 5 V output for input bias voltages greater than 5.5 V. Wide bias voltage range 3.0 V to 20 V
Wide power stage input range 1 V to 24 V
Wide output voltage range: 0.6 V to 85% of input voltage
±0.85% accuracy at 0oC to 70oC
All N-channel MOSFET design for low cost
Fixed-frequency operation at 300 kHz, 600 kHz, or resistor
adjustable 300 kHz to 600 kHz
Clock output for synchronizing other controllers
No current sense resistor required
Internal linear regulator
Voltage tracking for sequencing
Soft start and thermal overload protection
Overvoltage and undervoltage power-good indicator …
