LM2623MM Datasheet PDF - TI

●The LM2623MM is a high-efficiency general-purpose Step-up DC-DC Switching Regulator for battery-powered and low input voltage systems. It accepts an input voltage between 0.8 and 14V and converts it into a regulated output voltage between 1.24 and 14V. Efficiencies up to 90% are achievable with the LM2623. In order to adapt to a number of applications, the regulator allows the designer to vary the output voltage, the operating frequency (300kHz to 2MHz) and duty cycle (17 to 90%) to optimize the part"s performance. The selected values can be fixed or can vary with battery voltage or input to output voltage ratio. The regulator uses a very simple, on/off regulation mode to produce good efficiency and stable operation over a wide operating range. It normally regulates by skipping switching cycles when it reaches the regulation limit (Pulse Frequency Modulation).

● Up to 90% regulator efficiency

● Good efficiency over a very wide load range

● 0.17R Internal MOSFET

● Very low output voltage ripple

●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
