40V/2A Regulator Module Sports A Trim Profile

The LTM8063 40-Vin, 2A µModule step-down regulator resides in a 6.25 mm x 4 mm BGA package, reportedly 75% smaller than the existing equivalent device. With two 0805 size capacitors and two 0603 size resistors, the device measures 70 mm². Its Silent Switcher architecture minimizes EMI emissions, enabling the LTM8063 to pass the CISPR 22 class B EMC standard.


The LTM8063 delivers 2A (2.5A peak) continuous output current from 12 Vin to 5 Vout at an ambient temperature of +85°C. Its 40V input voltage allows it to safely operate from unregulated or fluctuating 12V to 24V input supplies in noisy environments. Output voltage is adjustable with one resistor from 0.8V to 15V.

Via an external resistor, switching frequency can be set ranging from 200 kHz to 2.2 MHz or can be synchronized to an external clock. Four operating modes are available: Burst Mode operation, pulse-skipping mode, pulse-skipping mode with spread spectrum modulation, and external sync mode. The combination of Silent Switcher architecture, wide operating frequency range, and multiple operating modes minimizes the risk of electromagnetic interference, ideal for noise- sensitive signal processing applications including imaging and RF systems.


The LTM8063 operating temperature range is –40°C to +125°C. Pricing starts at $6.95 each/1,000. For more information, a datasheet is available. Analog Devices Inc.
