Voltage Regulators - DC DC Switching Regulators datasheet and documents for LT1070MKJB

LT1070MKJB

Voltage Regulators - DC DC Switching Regulators Overview

The LT1070MKJB is a switching voltage regulator controller manufactured by Texas Instruments. It supports multiple converter topologies including boost, buck, flyback, and inverting configurations. The device operates with an input voltage range of 3 V to 40 V and features a fixed switching frequency of 40 kHz. Designed for through-hole mounting in TO-220-5 packages, it functions within a temperature range of 0 °C to +100 °C. The unit draws a typical operating supply current of 6 mA.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Supports versatile power conversion topologies such as boost, buck, and flyback
Operates across a wide input voltage range up to 40 V
Integrates internal oscillator for fixed-frequency switching control

Voltage Regulators - DC DC Switching Regulators Applications

DC-DC step-up (boost) converter circuits
DC-DC step-down (buck) converter designs
Inverting power supply architectures

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation carefully, as Analog Devices also produces the LT1070 series. Confirm the specific suffix 'MKJB' corresponds to the intended Texas Instruments variant rather than generic equivalents. Ensure the TO-220-5 package type matches the thermal and mechanical requirements of the target PCB layout before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a multi-topology switching controller is required for industrial or commercial power supplies. It is suitable for applications needing adjustable output voltages from a 3 V to 40 V input range. Consider the 40 kHz switching frequency for standard passive component sizing. Verify that the through-hole TO-220-5 package aligns with assembly capabilities and thermal dissipation needs.

Voltage Regulators - DC DC Switching Regulators Part Context

The LT1070 is a legacy high-efficiency switching regulator controller originally developed by Linear Technology, now part of Analog Devices. While Texas Instruments lists this specific MKJB variant, the core architecture is widely recognized for its flexibility in supporting various isolated and non-isolated DC-DC converter designs. It serves as a foundational control IC for custom power management solutions requiring robust performance across varying load conditions.
