Регуляторы напряжения - Импульсные регуляторы MAX662AEPA+

Фиксированный DC/DC преобразователь напряжения с подкачкой заряда без индуктора , 4.5В - 5.5В вход

The MAX662AEPA+ is a +12V, 30mA flash memory programming supply in 8 pin DIP package. It provides the necessary +12V ±5% output to program byte-wide flash memories and requires no inductors to deliver a 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 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 supply current to only 0.5µA. Typical applications include +12V flash memory programming supplies, compact +12V op-amp supplies, switching MOSFETs in low-voltage systems and dual-output +12V and +20V supplies.

• Supply voltage range is 4.5V to 5.5V
• Operating temperature range from -40°C to 85°C
• Quiescent current is 185µA
• Oscillator frequency is 500KHz
• Power efficiency is 76%
