The TPS40040EVM-001 evaluation module (EVM) is a synchronous buck converter providing a fixed1.8 V output at up to 10 A from a 5 V input bus. The EVM is designed to start up from a single supply, so no additional bias voltage is required for startup. The module uses the TPS40040 reduced pin count, low-voltage, synchronous buck controller.
Features
- 4.5 V to 5.5 V input range
- 1.8 V fixed output, adjustable with single resistor
- 10 A dc steady-state output current
- 300 kHz switching frequency (fixed by TPS40040)
- Single main switch MOSFET for both main switch and synchronous rectifier
- Double-sided 2 active layer PCB with all components on top side
- Active converter area of less than 1.5 in.² (i.e., <1.4 in. x 1.0 in.)
- Convenient test points for probing switching waveforms and noninvasive loop response testing
