Figure 40. Required External Components, Recommended Values, External Connections
The TPS65800 has two highly efficient step down synchronous converters. The integration of the power stage
switching MOSFETs reduces the external component count, and only the external output inductor and filter
capacitor are required. The integrated power stage supports 100% duty cycle operation. Multiple operation
modes are available, enabling optimization of the overall system performance under distinct load conditions.
The converters have two modes of operation: a 1.5 MHz fixed frequency pulse width modulation (PWM) mode at
moderate to heavy loads, and a pulse frequency modulation (PFM) mode at light loads. The converter output
voltage is programmable via I2C registers SM1_SET1 and SM2_SET1.
When the SM1/SM2 converters are disabled an integrated switch automatically discharges the converter output
capacitor. The discharge switch function can be disabled by setting the control bits DISCHSM1 and DISCHSM2
to LO, in I2C registers SM1_SET2 and SM2_SET2.
