Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2593HVS-3.3/NOPB

LM2593HVS-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2593HVS-3.3/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, designed for high-voltage input applications up to 60 V. It provides a fixed 3.3 V output with a maximum load current of 2 A. The device operates at a fixed switching frequency of 150 kHz and features an integrated power switch. It is housed in a TO-263-8 (D2PAK) surface-mount package, supporting operation across a temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-current power switch rated for 2 A continuous load
Fixed 150 kHz internal oscillator for simplified external component selection
Built-in thermal shutdown and current limit protection mechanisms

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for digital logic circuits
Pre-regulation for downstream linear regulators
Battery-powered systems requiring efficient step-down conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '3.3' confirms the fixed 3.3 V output variant. Confirm the 'NOPB' designation indicates lead-free and RoHS compliance. Ensure the 'S' suffix corresponds to the TO-263-8 package style. Cross-reference the manufacturer datasheet for any recent pinout or electrical specification updates.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V output is required from inputs up to 60 V. It is suitable for designs needing 2 A output current without external pass transistors. Consider the 150 kHz frequency for balancing efficiency and passive component size. Evaluate thermal performance requirements given the single-chip power switch integration.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2593HV series of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM2590 and LM2592 series but offers higher output current capability compared to the 1 A variants. The HV designation indicates suitability for high-input voltage environments.
