ADP1109
ObsoleteMicropower Low Cost Fixed 3.3 V, 5 V, 12 V and Adjustable DC-DC Converter
Part Details
The ADP1109 is a versatile step-up switching regulator. The device requires only minimal external components to operate a complete switching regulator.
The ADP1109-5 can deliver 100 mA at 5 V from a 3 V input, and ADP1109-12 can deliver 60 mA at 12 V from a 5 V input. The device also features a logic controlled shutdown capability that when a logic low is applied it will shut the oscillator down. The 120 kHz operating frequency allows for the use of small surface mount components.
The gated oscillator capability eliminates the need for frequency compensation.
