Additional Details

The ADP2387 is a synchronous step-down, dc-to-dc regulator with an integrated 44 mΩ, high-side power, metal oxide semiconductor field effect transistor (MOSFET) and an 11 mΩ, synchronous rectifier MOSFET to provide a high efficiency solution in a compact 4 mm × 4 mm LFCSP. This device uses a peak current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response. The switching frequency of the ADP2387 can be programmed between 200 kHz to 1400 kHz.

The ADP2387 requires minimal external components and operates from an input voltage of 4.5 V to 20 V. The output voltage can be adjusted from 0.6 V to 90% of the input voltage and delivers up to 6 A of continuous current. Each IC draws less than 110 μA current from the input source when it is disabled.

This regulator targets high performance applications that require high efficiency and design flexibility. External compensation and an adjustable soft start function provide design flexibility. The power-good output and precision enable input provide simple and reliable power sequencing. The programmable current-limit function allows the inductor to be optimized by output current.

Other key features include undervoltage lockout (UVLO), overvoltage protection (OVP), overcurrent protection (OCP), short-circuit protection (SCP), and thermal shutdown (TSD).

The ADP2387 operates over the −40°C to +125°C junction temperature range and is available in a 24-lead, 4 mm × 4 mm LFCSP.

Product Detail

The ADP2387-EVALZ evaluation board is a complete 6 A, 20 V, step-down regulator solution that allows users to evaluate the performance of the ADP2387 with a near ideal printed circuit board (PCB) layout.

The programmable current-limit function allows the inductor to be optimized by output current. The peak current-limit threshold is preset to 9 A to ensure the 6 A output current capability. The switching frequency can be programmed between 200 kHz and 1.4 MHz, which provides the possibility for a stackable multiphase power solution.

The output of the ADP2387-EVALZ evaluation board is preset to 3.3 V, and the switching frequency is set to 600 kHz. Different output voltage settings can be achieved by changing the appropriate passive components. The ambient temperature operating range is −40°C to +85°C.
