One side of the full bridge is driven by a pulse width modulation (PWM) buck power stage, while the other side of the full bridge is driven by a linear power stage. The LT8722 can deliver up to 54W of power to meet the needs of the latest thermoelectric coolers (TEC). An integrated 25-bit digital-to-analog converter (DAC) is used to control the output voltage and minimize temperature variation. Furthermore, Silent Switcher techniques are used to minimize EMI/EMC emissions while delivering high efficiency at high switching frequencies.
- Key Features and Benefits
- • 25-bit digital output voltage control
- • Silent Switcher techniques minimize EMI/EMC emissions to reduce or eliminate shielding requirements
- • Smallest solution size (3mm x 3mm LQFN) reduces PBC space and BOM list for a cost-effective solution
- Applications
- • Instrumentation
- • Communication: 5G
- • Building and Infrastructure
- • Healthcare
- Evaluation Board
- The LT8722 can be evaluated with the DC3145A.
