15mm x 9mm x 2.42mm package provided

Linear Technology Korea (CEO Hong Sa-kwak) announced the release of a dual-output DC/DC µModule® (power module) regulator (product name: LTM8049) with two functions, available in a 15mm x 9mm x 2.42 BGA package.

The first key feature of the LTM8049 is the SEPIC (single-ended primary-inductor converter), which enables a regulated output voltage even when the input voltage is lower, equal to, or higher than the output voltage. The second feature is inverting conversion, which converts a positive input voltage into a regulated negative output voltage. As a dual regulator, the output of the LTM8049 can be configured with a combination of SEPIC and/or inverting functions as follows.

In particular, compared to existing discrete solutions that require around 30 components, it is simple enough to complete the design with only seven components, such as input and output capacitors and a few resistors. Additionally, the PCB area of a solution using the LTM8049 is only 250mm². Applications include battery-powered portable test systems, motor drivers, and operational amplifier power supplies for measurement devices.

The LTM8049 operates in an input voltage range of 2.6V to 20V, and the range of each of the two output voltages is ±2.5V to ±24V. The output current is 1A at 12VIN/5VOUT and may increase when driving parallel devices. The operating frequency range, set via a single external resistor, is 200kHz to 2.5MHz. The LTM8049 can be synchronized via an external clock within the same frequency range and is available in a 9mm x 15mm x 2.42mm BGA package.

The operating temperature range of the LTM8049 is –40℃ to 125℃. The product price starts at $14.20 per unit based on a quantity of 1,000.
