1 / 5 page  www.belling.com.cn 1 +12V, 30mA Flash Memory Programming Supply BL8052 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. FEATURES Regulated +12V ±5% Output Voltage 4.5V to 5.5V Supply Voltage Range Fits in 0.1in2 Guaranteed 30mA Output No Inductor—Uses Only 4 Capacitors 95μA Quiescent Current Logic-Controlled 0.3μA Shutdown 8-Pin Narrow SO and DIP Packages APPLICATIONS +12V Flash Memory Programming Supplies Compact +12V Op-Amp Supplies Switching MOSFETs in Low-Voltage Systems Dual-Output +12V and +20V Supplies TYPICAL APPLICATION PIN OUT & MARKING BL8052 BL8052 |
