DESCRIPTION (CONTINUED)
A perfect fit for space-constrained, battery-powered applications, the LM2750 requires only 3 external
components: one input capacitor, one output capacitor, and one flying capacitor. Small, inexpensive ceramic
capacitors are recommended for use. These capacitors, in conjunction with the 1.7MHz fixed switching frequency
of the LM2750, yield low output voltage ripple, beneficial for systems requiring a low-noise supply. Pre-regulation
minimizes input current ripple, reducing input noise to negligible levels.
A tightly controlled soft-start feature limits inrush currents during part activation. Shutdown completely
disconnects the load from the input. Output current limiting and thermal shutdown circuitry protect both the
LM2750 and connected devices in the event of output shorts or excessive current loads.
