SEPICster step up/down converters
The SEPICster modules are fixed value DC-DC converters that can perform both step up and step down conversion seamlessly. This enables application where the power source voltage range encompasses the desired output voltage. The converters provide a stable output over a wide input supply range (2V to 19V) under various load conditions.
PGCPSU DUO Kit
PGCPSU is a three-in-one power supply board: it integrates a lithium battery charge management circuit with 5V and 3.3V DC-DC converter-based output rails to power most projects in a very compact form factor. Comes with our awesome 2600mAh 18650 lithium cell!
µBoost – that tiny boost converter
An ultra compact 3.3v out boost converter targetted at low and ultra low power applications. Super low quiescent current!
