BL8052
+12V, 30mA Flash Memory Programming Supply
DESCRIPTION
The BL8052 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 BL8052 is a pin-compatible
upgrade to the BL8052, and is recommended for
new designs. The BL8052 offers lower quiescent
and shutdown currents, and guarantees the
output current over all temperature ranges.
The BL8052 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 BL8052 comes in 8-pin
narrow SO and DIP packages.
