ADP2102 Datasheet Synchronous Step-down DC-dc Converter

Manufacturer: Analog Devices

Overview: Data Sheet Low Duty Cycle, 600 mA, 3 MHz, Synchronous Step-Down DC-to-DC Converter.

General Description

The ADP2102 is a synchronous step-down dc-to-dc converter that converts a 2.7 V to 5.5 V unregulated input voltage to a lower regulated output voltage with up to 95% efficiency and 1% accuracy.

The low duty cycle capability of the ADP2102 is ideal for USB applications or 5 V systems that power up submicron subvolt processor cores.

Its 3 MHz typical operating frequency and excellent transient response allow the use of small, low cost 1 µH inductors and 2.2 µF ceramic capacitors.

Key Features

  • Input voltage range: 2.7 V to 5.5 V 600 mA maximum load current 95% efficiency Low duty cycle operation Only 3 tiny external ceramic components 3 MHz typical operating frequency Fixed output voltage of 1.2 V or 1.375 V Adjustable output voltage up to 3.3 V 0.01 µA shutdown supply current Automatic power save mode Internal synchronous rectifier Internal soft start Internal compensation Enable/shutdown logic input Undervoltage lockout Current limit protection Thermal shutdown Small 8-lead, 3 mm ×.
