Torex Semiconductor, Ltd. PMIC - Voltage Regulators - DC DC Switching Regulators XC9282B33E0R-G

The XC9282B33E0R-G is a synchronous rectification DC/DC converter designed for step-down applications, capable of delivering up to 600mA output current. It operates within an input voltage range of 2.5V to 5.5V and provides a fixed output voltage of 3.3V with a tolerance of ±1.5%. The device features HiSAT-COT control technology, which enhances transient response and minimizes output voltage fluctuations during load changes, making it suitable for applications requiring stable power supply, such as mobile devices and wearables. The XC9282B33E0R-G has a quiescent current of 11OºA and operates efficiently with a maximum efficiency of 90% at a 4MHz oscillation frequency. It is packaged in a compact LGA-6B01 form factor measuring 1.2 x 1.2 x 0.3mm, which is advantageous for space-constrained designs. The device includes protection features such as current limit, soft-start, and under-voltage lockout (UVLO), ensuring reliable operation in various conditions. Additionally, it is compliant with EU RoHS standards, making it an environmentally friendly choice for engineers.
