One converter is designed with a 100mA current limit and a 400ns off-time, while the other has a 175mA current limit and a 1.5µs off-time. The 1.5µs off-time converter is ideal for generating an output voltage close to the input voltage, such as a Li-Ion to 5V converter or a two-cell to 3.3V converter. With an input voltage range of 1.2V to 15V, the LT1944-1 suits a wide variety of applications. Both converters feature a quiescent current of only 20µA at no load, which reduces further to 0.5µA in shutdown. A current-limited, fixed off-time control scheme conserves operating current, resulting in high efficiency over a broad range of load current. Tiny, low-profile inductors and capacitors can be used to minimize footprint and cost in space-conscious portable applications. Applications include small TFT LCD panels, handheld computers, battery backup systems, and digital cameras.\u003c\/p\u003e\n  \u003cul\u003e\n   \u003cli\u003eQuiescent current (each switcher) is 20µA typical at (not switching, TA = 25°C)\u003c\/li\u003e\n   \u003cli\u003eSwitch VCESAT is 85mV typical at (ISW = 70mA, TA = 25°C)\u003c\/li\u003e\n   \u003cli\u003eFB pin bias current is 30nA typical at (VFB = 1.23V)\u003c\/li\u003e\n   \u003cli\u003eSwitch leakage current is 0.01µA typical at (switch off, VSW = 5V, TA = 25°C)\u003c\/li\u003e\n   \u003cli\u003eFB comparator hysteresis is 8mV typical at (TA = 25°C)\u003c\/li\u003e\n   \u003cli\u003eFB voltage line regulation is 0.05%\/V typical at (1.2V \u0026lt;
