General Description
The MAX1760/MAX1760H are high-efficiency, low-noise, step-up DC-DC converters intended for use in battery powered wireless applications. They combine low quiescent supply current (100µA) with a high 1MHz operating frequency. Small external components and tiny 10-pin TDFN and µMAX® packages make this device an excellent choice for small hand-held applications.
