一,产品概述(General Description)
The CXTP6508 is a regulated +12V, 30mA-output,chargepump 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 CXTP6508 is a pin-compatible
upgrade to the CXTP6508, and is recommended for new designs. The CXTP6508 offers
lower quiescent and shutdown currents, and guarantees the output current over all
temperature ranges.
The CXTP6508 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.A logic-controlled shutdown pin that interfaces directly
with microprocessors reduces the supply current to only 0.3μA. The CXTP6508 comes in
8-pin narrow SO and DIP packages.
