Analog Devices Inc. ADPL16000 DC-DC Converters

Analog Devices Inc. ADPL16000 DC-DC Converters are high-efficiency, high-voltage, synchronous DC-DC converters with integrated MOSFETs. These step-down converters operate at a wide input voltage range of 4.5V to 60V. The ADPL16000 converters can deliver up to 400mA and generate output voltages from 0.9V to 0.89 x Vin. These DC-DC converters feature the flexibility to support multiple rails in a system and operate reliably in adverse industrial environments. The devices use a peak-current-mode control architecture with a MODE pin used to operate the device in Pulse-Width Modulation (PWM) or Pulse-Frequency Modulation (PFM) control. These converters are available in a compact 8-pin 2mm x 2mm TDFN-CU package. The ADPL16000 converters are ideal for industrial sensors, 4mA to 20mA current loops, HVAC and building control, high-voltage LDO replacement, and general-purpose Point-of-Load (POL).
