Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM3370SDX-3021/NOPB

LM3370SDX-3021/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3370SDX-3021/NOPB is a dual synchronous step-down DC-DC converter manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 5.5 V and provides two independent output channels with fixed voltages of 1.2 V and 1.85 V. Each channel supports a maximum output current of 600 mA. The device integrates a 2 MHz switching frequency and utilizes a WSON-16 surface-mount package. It functions reliably across an operating temperature range from -30°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Dual synchronous buck topology for efficient power conversion
Integrated dynamic voltage scaling capability
Fixed internal feedback resistors for simplified design

Voltage Regulators - DC DC Switching Regulators Applications

Portable electronic devices requiring multiple low-voltage rails
Embedded systems with strict space constraints
Battery-powered equipment needing high efficiency

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '3021' confirms the 1.2 V and 1.85 V fixed output configuration. Ensure the 'NOPB' designation indicates lead-free and RoHS compliance. Confirm the 'SDX' prefix corresponds to the tape-and-reel packaging format required for automated assembly processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact dual-output solution is required for inputs up to 5.5 V. The fixed voltage options eliminate external resistor networks, reducing board space. Verify that the 600 mA per channel rating meets the load requirements for both target circuits simultaneously.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3370 family of dual synchronous step-down converters. It shares core architecture with variants like the LM3370SD-3416 but differs in fixed output voltage settings. The SDX suffix denotes reel packaging, distinguishing it from cut-tape or tube alternatives within the same electrical specification set.
