The ADP2443 is synchronous step-down, dc-to-dc regulator with an integrated 98 m?, high-side power metal oxide semicon-ductor field effect transistor (MOSFET) and a 35 m?, synchronous rectifier MOSFET to provide a high efficiency solution in a compact 4 mm ? 4 mm LFCSP package. The regulators operate from an input voltage range of 4.5 V to 36 V. The output voltage can be adjusted down to 0.6 V and deliver up to 3 A of continuous current. The fast 50 ns minimum on time allows the regulators convert high input voltage to low output voltage at high frequency.The ADP2443 uses an emulated current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response. The switching frequency of the ADP2443 can be programmed from 200 kHz to 1.8 MHz. The synchronization function allows the switching frequency be syn-chronized with an external clock to minimize the system noise.The ADP2443 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.Other key features include undervoltage lockout (UVLO), overvoltage protection (OVP), overcurrent protection (OCP), short-circuit protection (SCP), and thermal shutdown (TSD).The ADP2443 operates over the ?40?C to +125?C operating junction temperature range and is available in a 24-lead, 4 mm ? 4 mm LFCSP package.Applications Intermediate power rail conversion Multicell battery powered systems Process control and industrial automation Healthcare and medical Networking and servers
