Linear Launches 42VIN, 3.5A μModule Regulator for Industrial and Aerospace
Published2016.06.15 11:37Linear Technology Korea (CEO Hong Sa-kwak) announced the release of the µModule® (Power Module) step-down regulator (product name: LTM8053) with a maximum input of 40V (absolute rating 42V). This product can safely operate with poorly regulated or highly variable 12V to 36V input power in noisy environments such as industrial robots, factory automation, and aviation systems.
The LTM8053 integrates a switching regulator controller, power switch, inductor, and other supporting components into a 6.25mm x 9mm x 3.32mm BGA package. Since it requires only two external capacitors and two resistors, the LTM8053 solution size is only about 150mm². Alternative solutions require up to 250mm² in size and roughly twice the number of external components.
The LTM8053 provides a continuous (6A peak) output current of 3.5A, and the SHARE pin enables current sharing, supporting operation to deliver more current in parallel. The output voltage can be adjusted by a single resistor within the range of 0.97V to 15V. The wide output voltage range provides versatility. Thus, a single device generates common system bus voltages of 3.3V, 5V, 12V, and 15V. The efficiency is 90% at 12VIN, 5VOUT. The LTM8053 provides an output current of 3.5A at an ambient temperature of up to 85°C (12VIN ~ 5VOUT) without a heat sink or airflow.
The operating temperature range of the LTM8053 is –40°C to 125°C. The price per unit is $9.66 based on a quantity of 1,000. For more information, please refer to www.linear.com/product/LTM8053.

Linear Releases DC/DC Controller Using Single Inductor and Ground Reference Control
Linear Technology Korea (Representative Hong Sa-gwak) announced the release of a high-voltage inverting switching regulator controller (product name: LTC3896) that drives all N-channel synchronous MOSFET power stages. Most low-power or mid-level inverting DC/DC converters use coupled inductors or transformers. However, the LTC3896 uses only a single inductor and converts a positive input voltage of 4V to (150V − |VOUT|) into a regulated negative output voltage in the range of −60V to −0.8V at a maximum output current of 15 amperes. With maximum efficiency of 96%, it is ideal for transportation, industrial, telecom, and power distribution applications.

Linear Launches Synchronous Step-Down Regulator Operating at Up to 175°C
Linear Technology Korea (CEO Hong Sa-gwak) announced the launch of a synchronous step-down switching regulator (product name: LT8610AX) with 42V input and 3.5A output. The device operates even at ambient temperatures up to 175°C. Synchronous rectification delivers high efficiency at 95%, while Burst Mode® operation maintains standby current at 3.5μA or less under no-load idle conditions. The product's 3.7V ~ 42V input voltage range makes it ideal for high-temperature applications such as down-hole drilling equipment where the power source falls within the 5V ~ 40V range.
