Product Introduction

Overview

The LMZ21701SILT nano module, produced by Texas Instruments, is a highly integrated step-down DC/DC converter designed for space-constrained applications. This module is capable of driving up to 1000 mA of load current and operates within an input voltage range of 3 V to 17 V, with an adjustable output voltage from 0.9 V to 6 V. The LMZ21701SILT features a compact 3.5 mm × 3.5 mm × 1.75 mm package, making it ideal for applications where board space is limited. It incorporates an integrated inductor and uses Texas Instruments' DCS-Control™ architecture, which combines the benefits of hysteretic, voltage mode, and current mode regulators for efficient and stable operation.

Key Features

  • Compact Package: 3.5 mm × 3.5 mm × 1.75 mm MicroSiP™ package with an integrated inductor, ideal for space-constrained applications.
  • Adjustable Output Voltage: Output voltage can be adjusted from 0.9 V to 6 V using a resistive voltage divider.
  • High Efficiency: Up to 95% efficiency, ensuring minimal heat generation and high performance.
  • Soft-Start and Tracking Function: Features a soft-start function and tracking capability to manage the output voltage rise and sequencing.
  • Power Good and Enable Pins: Includes power good (PG) and enable (EN) pins for monitoring and controlling the module.
  • Thermal Protection: Integrated thermal protection that shuts down the device if the junction temperature exceeds 160°C.
  • Input Undervoltage Lockout (UVLO): Prevents the device from switching if the input voltage is below a certain threshold.
  • Output Current Limit and Short Circuit Protection: Protects against heavy loads and output short circuits by monitoring and controlling the current.

Applications

  • Point-of-Load Conversions: Suitable for point-of-load conversions from 3.3 V, 5 V, or 12 V input voltages.
  • Space-Constrained Applications: Ideal for applications where board space is limited, such as in portable electronics, IoT devices, and other compact systems.
  • LDO Replacement: Can be used as a replacement for linear voltage regulators (LDOs) to improve efficiency and reduce heat generation.
