LMR16006YDDCT

Voltage Regulators - DC DC Switching Regulators Overview

The LMR16006YDDCT is a SIMPLE SWITCHER® 60 V, 0.6 A buck regulator from Texas Instruments. It operates with an input voltage range of 4 V to 60 V and delivers up to 600 mA output current. The device features a fixed switching frequency of 2.1 MHz and ultra-low standby current of 28 µA in Eco-mode. Shutdown current is 1 µA. Output voltage is adjustable from 0.765 V to 55 V. It includes internal compensation, soft start, overcurrent protection, and thermal shutdown. The component is housed in a SOT-23-THIN-6 (TSOT-23-6) package and supports operation temperatures from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'Y' confirms the 2.1 MHz switching frequency variant, distinct from the 'X' version which operates at 700 kHz. Ensure the package designation matches SOT-23-THIN-6. Confirm RoHS compliance status via the manufacturer datasheet. Validate that the specific revision level meets project requirements. Cross-reference the ordering part number with official Texas Instruments documentation to avoid substitution errors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a high-efficiency step-down converter is required for inputs up to 60 V. The 2.1 MHz frequency is optimal for minimizing passive component size compared to lower frequency alternatives. Choose this part if ultra-low quiescent current is critical for battery-operated applications. Ensure the load current does not exceed the 600 mA rating. Verify thermal performance within the specified operating temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LMR16006 series of SIMPLE SWITCHER regulators. The series offers high efficiency and small solution sizes. The Y suffix specifically denotes the 2.1 MHz switching frequency option. The X suffix denotes the 700 kHz option. Both share similar electrical characteristics but differ in switching speed and associated filter component values.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR16006XDDCT is a functional substitute with identical pinout and electrical ratings, differing only in switching frequency (700 kHz vs 2.1 MHz). Component selection must be adjusted accordingly.
