The LM5642XMHX/NOPB from Texas Instruments is a high voltage, dual synchronous buck converter controller designed for efficient power management. It operates with an input voltage range of 4.5V to 36V and features two synchronous buck regulators operating 180° out of phase.
This controller boasts a nominal switching frequency of 375kHz, with the ability to synchronize to an external clock between 200 kHz and 500 kHz. Key electrical features include adjustable output from 1.3V to 90% of Vin, a typical shutdown current of 50 µA, and adjustable cycle-by-cycle current limit. It also incorporates essential control features like enable and soft start, along with input under-voltage lockout and output over-voltage latch protection.
The LM5642XMHX/NOPB is housed in a 28-pin HTSSOP package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ). The device is configurable for single output parallel operation, offering design flexibility. This component is ideal for applications requiring precise and efficient DC-DC conversion.
