What are the key features of LM2765M6X NOPB?
- Inductor-free charge pump topology boosts 3.6 V input to 11 V output using only small external capacitors, minimizing EMI
- 20 mA output current capability supports LCD bias supply and small white-LED string drive from a single 3.6 V to 5 V rail
- Ultra-compact 6-pin SOT-23 package occupies under 5 mm squared of PCB area, enabling integration in space-constrained portable designs
What is LM2765M6X NOPB used for?
The LM2765M6X NOPB is designed for portable consumer electronics such as mobile phones, PDAs, and handheld game consoles that need a small inductorless boost converter to generate LCD bias or OLED drive voltages from a single-cell lithium-ion battery. Its 11V output is particularly suited for driving small TFT LCD panels that require a gate driver bias rail above the battery voltage. The device is also used in portable medical monitors and handheld industrial scanners needing a compact high-voltage auxiliary supply.

Frequently Asked Questions
What input voltage range and maximum output current does the LM2765M6X NOPB support?
The LM2765M6X NOPB accepts an input from 3.6 V and boosts it to a regulated 11 V output with up to 20 mA of load current. This output level and current capacity are matched to the LCD bias supply requirements of small TFT displays and OLED panels commonly used in portable consumer and medical devices.
Why is an inductor-free charge pump architecture advantageous in portable handheld designs?
Eliminating the inductor removes a large, expensive magnetic component and its associated EMI radiation, replacing it with two small ceramic capacitors typically valued at 100 nF to 1 µF. This reduces the converter footprint by over 50 percent compared to an equivalent inductive boost design, simplifies EMC compliance, and lowers BOM cost by approximately 30 to 50 cents per unit.
How does the LM2765M6X NOPB compare to a discrete diode-capacitor voltage doubler for driving an 11 V LCD bias rail?
Unlike a passive diode-capacitor doubler, the LM2765M6X NOPB provides a regulated 11 V output that remains stable across a 3.6 V to 5 V input range and a 0 to 20 mA load swing. A passive multiplier cannot regulate its output, causing LCD contrast to shift by several volts as battery voltage drops from 4.2 V to 3.6 V, degrading display quality in field use.
What external components are required around the LM2765M6X NOPB, and how does this affect time-to-market?
The LM2765M6X NOPB requires only 2 to 3 external ceramic capacitors in the range of 100 nF to 1 µF, with no inductors, transformers, or resistor networks. This minimal BOM allows an engineer to complete schematic capture and PCB layout in less than 1 hour, shortening time-to-market for LCD-equipped portable products by several days compared to an equivalent inductive topology.
