Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9236C1LC4R-G

The XC9236C1LC4R-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 using two resistors, or it can be fixed at various levels from 0.8V to 4.0V depending on the specific type. The device features a built-in 0.42Oc P-channel MOS driver transistor and a 0.52Oc N-channel MOS switching transistor, allowing for the use of ceramic capacitors. The XC9236C1LC4R-G operates in automatic PWM/PFM switching control mode, which optimizes efficiency across a wide load range. It includes a soft start function, a current limiter, and an under-voltage lockout (UVLO) feature that disables the output when the input voltage drops below 1.4V. The device is available in multiple package options, including SOT-25 and USP-6C, and is compliant with EU RoHS standards. This regulator is suitable for applications in mobile devices, Bluetooth devices, and portable game consoles, among others.
