LM2750

Low Noise Switched Capacitor Boost Regulator

General Description

Features

n Inductorless solution: Application requires only 3 small

ceramic capacitors

The LM2750 is a regulated switched-capacitor doubler that

produces a low-noise output voltage. The 5.0V output volt-

age option (LM2750-5.0) can supply up to 120mA of output

current over a 2.9V to 5.6V input range, as well as up to

40mA of output current when the input voltage is as low as

2.7V. An adjustable output voltage option with similar output

current capabilities is also available (LM2750-ADJ). The

LM2750 has been placed in National’s 10-pin LLP, a pack-

age with excellent thermal properties that keeps the part

from overheating under almost all rated operating conditions

n Fixed 5.0V output and adjustable output voltage options

available

n 85% Peak Efficiency

70% Average Efficiency over Li-Ion Input Range

(2.9V-to-4.2V)

n Output Current up to 120mA with 2.9V ≤ V_IN≤ 5.6V

Output Current up to 40mA with 2.7V ≤ V_IN≤ 2.9V

n Wide Input Voltage Range: 2.7V to 5.6V

n Fixed 1.7MHz switching frequency for a low-noise,

low-ripple output signal

n Pre-regulation minimizes input current ripple, keeping

the battery line (V_IN) virtually noise-free

n Tiny LLP package with outstanding power dissipation:

Usually no derating required.

A perfect fit for space-constrained, battery-powered applica-

tions, the LM2750 requires only 3 external components: one

input capacitor, one output capacitor, and one flying capaci-

tor. Small, inexpensive ceramic capacitors are recom-

mended 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.

n Shutdown Supply Current less than 2µA

Applications

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.

n White and Colored LED-based Display Lighting

n Cellular Phone SIM cards

n Audio Amplifier Power Supplies

n General Purpose Li-Ion-to-5V Conversion
