Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9237E36DER-G

The XC9237E36DER-G is a synchronous step-down DC/DC converter designed to provide a stable output voltage with high efficiency. It operates within an input voltage range of 2.0V to 6.0V and can deliver an output current of up to 600mA. The output voltage can be set externally from 0.9V to 6.0V, or it can be fixed at 3.6V, making it versatile for various applications. This regulator features a built-in P-channel MOS driver transistor with a low on-resistance of 0.42Oc and an N-channel MOS switching transistor with 0.52Oc, which contributes to its efficiency, typically reaching 92%. The device supports both PWM control and automatic PWM/PFM switching modes, allowing for optimized performance across different load conditions. Additional features include a soft-start function, a built-in under-voltage lockout (UVLO) function, and a low standby current consumption of 1.0OºA or less. The XC9237E36DER-G is suitable for applications in mobile devices, smartphones, and portable game consoles, among others. It is available in multiple package types, including SOT-25 and USP-6C, ensuring compatibility with various PCB designs.
