An introduction to TDK's micro-POL chip embedded power module technology. Shown is the FS1406, 6A Rated μPOL™ Buck Regulator with Integrated Inductor and Digital Power System Management. The FS1406 is an easy-to-use, fully integrated and highly efficient micro-point-of-load (μPOL™) voltage regulator. The on-chip pulse-width modulation (PWM) controller and integrated MOSFETs, plus incorporated inductor and capacitors, result in an extremely compact and accurate regulator. The low-profile package is suitable for automated assembly using standard surface-mount equipment. Features • μPOL™ package with output inductor included • Small size: 3.3mm x 3.3mm x 1.5mm • Continuous 6A load capability • Plug and play: no external compensation required • Programmable operation using the I2C serial bus • Wide input voltage range: 4.5–16V • Adjustable output voltage: 0.6–2.5V, ±0.5% initial accuracy • Enabled input, programmable under-voltage lock-out (UVLO) circuit • Open-drain power-good indicator • Built-in protection features • Operating temperature from -40°C to +125°C • Lead-free and halogen-free • Compliant with EU Directives REACH and RoHS 6.
