DIODES Incorporated PMIC - PMIC - Voltage Regulators - DCDC Switching Regulators - PAM2321AYMADJ PAM2321AYMADJ

The PAM2321AYMADJ is a 2A step-down DC-DC switching regulator designed for efficient voltage regulation in portable applications. It operates with an input voltage range of 2.7V to 5.5V and offers a fixed output voltage of 1.2V or an adjustable output from 1.0V to VIN. The device features a high switching frequency of 3MHz, allowing for the use of small external components, which is beneficial for space-constrained designs. With a low no-load quiescent current of 55¬µA and integrated low RDS(ON) MOSFETs, the PAM2321AYMADJ is optimized for high efficiency across varying load conditions. It includes features such as 100% duty cycle operation for low dropout scenarios, internal soft-start, and protection mechanisms for over-temperature and short circuits, enhancing reliability in demanding applications. The regulator is housed in a compact TDFN3X3-10 package, rated for operation over a temperature range of -40¬8C to +85¬8C, making it suitable for a variety of environments. Typical applications include cellular phones, digital cameras, and portable media players, where efficient power management is critical.
