It takes a 3.5 V to 16.5 V input and delivers a fixed Vin+11 V output at up to 25 mA, switching at 90 kHz. The 8-SOIC package is surface-mount, rated for -40°C to +85°C operation, making it a fit for industrial and telecom bias supplies where a simple unregulated boost is acceptable. ## The Vin+11V output — what it means for your rail The fixed output of Vin+11 V means the output tracks the input with an 11 V offset. ## 90 kHz switching — capacitor sizing The 90 kHz switching frequency is on the lower side for a modern charge pump, which means the external flying and output capacitors will be larger in value (typically in the microfarad range) compared to a 1 MHz part. That's a trade-off: the lower frequency reduces switching losses and radiated noise, but takes up more board area. For a bias supply on a noisy industrial rail, the quieter switching is often worth the space. ## Package and rework The 8-SOIC package is a standard Gull-wing leaded part — easy to hand-solder or rework with hot air. ## Lifecycle and sourcing The MAX1822ESA+ is listed as Active and ROHS3 compliant.","metaTitle":"MAX1822ESA+ Charge Pump IC, 90kHz, 25mA, 8-SOIC","metaDescription":"MAX1822ESA+ ratiometric charge pump IC from Analog Devices.
