DC-DC преобразователи интегральные ADM8829ARTZ-REEL7

DC-DC импульсный инвертирующий стабилизатор , 1.5В-5.5В (Vin), -5.5В--1.5В, 25мА, SOT-23-6

The ADM8829ARTZ-REEL7 is a switched-capacitor Voltage Inverter with shutdown function. The charge-pump voltage inverter which may be used to generate a negative supply from a positive input. Input voltage ranging from +1.5 to +5.5V can be inverted into a negative -1.5 to -5.5V output supply. This inverting scheme is ideal for generating a negative rail in single power-supply systems. Only two small external capacitors are needed for the charge pump. Output current up to 25mA with greater than 99% efficiency are achievable. The ADM8828 also features a low power shutdown (SHDN) pin. This can be used to disable the device and reduce the quiescent current to 20nA.
