LMZ21701SILR DC/DC Power Module
The LMZ21701SILR, manufactured by Texas Instruments, is a high-efficiency, easy-to-use 1A synchronous buck DC/DC power module from the SIMPLE SWITCHER® Nano series, integrating an inductor and all necessary passive components within a tiny 3.5×3.5×1.75mm 8-pin uSIP package. It accepts a wide input voltage range of 3V to 17V and delivers an adjustable output voltage from 0.9V to 6V, supporting up to 1A continuous output current with a peak efficiency of 95%. Designed for space-constrained and low-power applications, it features DCS-Control™ architecture with seamless PWM/Power Save Mode transition, ultra-low 17μA quiescent current and 1.5μA shutdown current, plus a wide -40°C to 125°C operating temperature range for industrial and automotive use.
This fully integrated power module eliminates the need for external inductors and complex compensation circuits, requiring only four external components (two resistors, two capacitors) for basic operation. It offers adjustable soft-start, power good (PGOOD) indicator, enable control, and pre-bias startup capability, ensuring reliable and flexible power sequencing. The device operates at a switching frequency of 1.25MHz to 2.5MHz, minimizing EMI and enabling compact PCB layout with a 35mm² single-sided solution size.
