The LM2623AMM is a general purpose gated oscillator based DC/DC Boost Converter 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% and in order to adapt to a number of applications, the LM2623 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 converter 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).
● 0.17R Internal MOSFET
● Good efficiency over a very wide load range
● Very low output voltage ripple
● Up to 90% regulator efficiency
● <2.5µA Ensured supply current in shutdown
●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.
