Key Features
- Integrated inductor in a compact LDFN-10-EP (2.8x3mm) power module simplifies design and dramatically reduces external component count
- 3A output current with 3V to 17V wide input range covers a broad set of industrial, communications, and embedded computing rails
- 2.5MHz switching frequency enables the use of tiny external ceramic capacitors for minimal solution footprint
- Ultra-low 4µA quiescent current with PWM and current-mode control maintains high efficiency from light to full load
Applications
The TPSM82903SISR is designed for industrial automation, telecom line cards, and embedded computing boards that require a compact, high-efficiency point-of-load regulator capable of converting 12V bus power down to core, I/O, or memory supply voltages. Its integrated inductor and wide input voltage range make it especially attractive for space-constrained PCBs in test equipment, robotics controllers, and factory automation nodes operating across harsh industrial temperature ranges.
