Some step-up DC/DC converter functions require input current limiting because of high source impedance or limited capability of power components. The LT1316, a micropower step-up DC/DC converter with peak switch current control, meets these needs. The device draws 33μA quiescent current and contains a 0.6Ω, 30V switch that can be programmed for a maximum peak current between 30mA and 600mA with an external resistor. It also has a low-battery detector ...
