DC611A - LTC3252EDE Demo Board | Dual, Spread-Spectrum, Low Noise Inductorless, Step Down Charge Pump, 2.7V ≤ VIN ≤ 5.5V, Vout1 = 1.5V @ 250mA, Vout2 = 1.2V@250mA

Demonstration circuit 611 is a dual, spread-spectrum, step-down charge pump DC/DC converter featuring the LTC®3252EDE. It produces regulated 1.5V and 1.2V output voltages at up to 250mA of output current each, from a 2.7V to 5.5V input. The unique spread spectrum architecture of the LTC3252 provides highly efficient, low noise operation. The circuit has a low external parts count and requires only five small surface mount capacitors and four tiny surface mount resistors.
