Shenzhen Meiyuxin Technology Co., Ltd. [TI Agent] Brand New LM2840YQMKX/NOPB 100mA step-down DC/DC regulator Quality assurance! ! !

Product Description:

The LM2840YQMKX/NOPB SIMPLE SWITCHER™ devices are PWM DC/DC buck regulators. With an input range of 4.5V to 42V, the device is suitable for a variety of applications (eg, power regulation from unregulated sources). They feature low RDSON (0.9Ω typ) internal switches for maximum efficiency (85% typ). Additionally, they feature fixed operating frequencies of 550kHz (X option) and 1.25MHz (Y option) to support small external components while maintaining low output voltage ripple. Soft-start can be performed by using the Shutdown (SHDN) pin in combination with an external RC circuit, allowing the user to adjust the soft-start time to the specific application.

The LM2840YQMKX/NOPB is optimized for load currents up to 100mA for the LM2840-Q1, 300mA for the LM2841-Q1, and 600mA for the LM2842-Q1. They all have a nominal feedback voltage of 0.765V.

LM2840YQMKX/NOPB This device also provides other features including thermal shutdown, VIN undervoltage lockout and gate drive undervoltage lockout. The LM284x-Q1 are all packaged in a low profile SOT-6L package.
