MAX662AESA+T

The MAX662AESA+T is a +12V, 30mA flash memory programming supply in 8 pin NSOIC package. This is a regulated +12V, 30mA output, charge pump DC-DC converter. It provides the necessary +12V ±5% output to program byte wide flash memories and requires no inductors to deliver a guaranteed 30mA output from inputs as low as 4.75V. It fits into less than 0.1in² of board space. The MAX662A is a pin compatible upgrade to the MAX662 and is recommended for new designs. The MAX662A offers lower quiescent and shutdown currents and guarantees the output current over all temperature ranges. The MAX662A is the first charge-pump boost converter to provide a regulated +12V output. It requires only a few inexpensive capacitors and the entire circuit is completely surface-mountable. Typically used at +12V flash memory programming supplies, compact +12V op-amp supplies, switching MOSFETs in low voltage systems and dual output +12V and +20V supplies.
