ADP2119ACPZ-R7 ADI synchronous buck converter
The ADP2119ACPZ-R7 from Analog Devices is a compact, high-efficiency synchronous step-down DC-DC converter delivering up to 2A continuous output current, optimized for low-voltage, battery-powered, and space-constrained systems. It operates with a 2.3V to 5.5V input voltage range and offers an adjustable output voltage from 0.6V to VIN, supporting common rails like 3.3V, 2.5V, 1.8V, and 1.2V. Housed in a 3mm × 3mm 10-lead LFCSP package with an exposed pad, it integrates low on-resistance power MOSFETs (145mΩ/70mΩ) and uses current-mode PWM control at a fixed 1.2MHz switching frequency, ensuring fast transient response, high efficiency (up to 95%), and minimal external component size. With a quiescent current of just 680µA and ultra-low 3µA shutdown current, it balances performance and power savings for energy-sensitive designs.
This converter integrates a robust set of features:
● wide 2.3V–5.5V input and 0.6V–VIN adjustable output
● 2A continuous/3A peak current capability; integrated 145mΩ high-side and 70mΩ low-side MOSFETs for high efficiency
● fixed 1.2MHz switching frequency for small inductors and capacitors; user-selectable PWM/PFM modes for light-load efficiency
● ±1.5% output voltage accuracy over temperature and load
● internal soft-start, current limit, thermal shutdown, and under-voltage lockout (UVLO) protections
● power-good (PG) indicator for system monitoring
Alternative Step-Down DC-to-DC RegulatorModels
● MP2307 (MPS): 3A, 4.5V–23V input synchronous buck converter in a SOT23-6 package, offering high efficiency and low EMI for industrial and consumer applications.
● T1763 (Analog Devices): 2A, 2.5V–16V input step-down converter with integrated MOSFETs, high efficiency, and comprehensive protections, ideal for battery-powered systems.
● RT8259 (Richtek): 2A, 2.5V–5.5V input synchronous buck regulator with low quiescent current and high efficiency, pin-compatible alternative for cost-sensitive designs.
