The UC3573DTR from Texas Instruments is a Buck pulse width modulator designed for step-down voltage regulation. It is optimized for use in single inductor buck switching converters, employing an external PMOS switch. This device features a wide input voltage range from 4.75V to 30V and can deliver an output current of up to 0.5A, with an adjustable output voltage range from 1.5V to 30V.
Key electrical characteristics include a maximum duty cycle of 92% and an operating frequency of 100kHz. The controller includes features such as undervoltage lockout (UVLO) and pulse-by-pulse current limit for robust operation. Its typical quiescent current is 0.009mA, with a low 50µA sleep mode current.
The UC3573DTR is housed in an 8-SOIC package, suitable for surface mount applications. It operates within an ambient temperature range of 0°C to 70°C. This component is ideal for power management applications requiring efficient step-down voltage conversion.
