Synchronous buck controller from the SIMPLE SWITCHER® family
The Texas Instruments LM3152MHE-3.3/NOPB is a single-phase synchronous buck controller from the SIMPLE SWITCHER® series, designed for step-down (buck) conversion. It integrates a transistor driver output and synchronous rectifier, which improves efficiency at higher output currents compared to asynchronous controllers. The fixed 500kHz switching frequency simplifies inductor selection and EMI filter design. With a supply range of 6V to 33V and an operating temperature range of -40°C to 125°C (TJ), it suits industrial power supplies, motor drives, and outdoor telecom equipment where wide input voltage and thermal robustness are required.
What the key ratings mean for your BOM
The 500kHz fixed switching frequency sets the inductor value and output capacitor ripple current.
Lifecycle and sourcing posture
The LM3152MHE-3.3/NOPB carries an Active product status and is ROHS3 compliant. For a BOM line that needs a synchronous buck controller with a fixed 3.3V output and a wide input range, this part is a clean, current-production choice.
