LM828M5 Description

Short technical summary and product information.

The LM828M5 from Texas Instruments is a CMOS charge-pump voltage converter designed to invert a positive input voltage to a corresponding negative output voltage. It accepts an input voltage range of +1.8V to +5.5V and provides an output voltage range of -1.8V to -5.5V.

 

This device utilizes two low-cost capacitors to deliver up to 25 mA of output current. Operating at a switching frequency of 12 kHz, the LM828M5 is engineered to minimize output resistance and voltage ripple. With a typical quiescent current of only 40 µA and operating efficiency greater than 96% for most loads, it is well-suited for battery-powered applications.

 

The LM828M5 features synchronous rectification and is available in a compact SOT-23-5 package, making it ideal for space-constrained designs. Its typical output impedance is 20 Ω, and it offers a typical conversion efficiency of 97% at 5 mA.

 

This voltage converter operates within a temperature range of -40°C to 85°C (TJ). Its surface mount capability and small package size facilitate easy integration into various electronic circuits.
