BL8052 Datasheet | BELLING

+12V, 30m A Flash Memory Programming Supply DESCRIPTION The BL8052 is a regulated +12V, 30m A-output, chargepump DC-DC converter. It provides the necessary +12V ±5% output to program bytewide flash memories, and requires no inductors to deliver a guaranteed 30m A output from inputs as low as 4.75V. It fits into less than 0.1in2 of board space. The BL8052 is a pin-patible upgrade to the BL8052, and is remended 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 pletely surface-mountable. A logic-controlled shutdown pin that interfaces directly with microprocessors reduces the supply current to only 0.3μA. The BL8052 es in 8-pin narrow SO and DIP packages.
