Table 2. Operation Mode Description MODE DESCRIPTION CONDITION PWM Boost in normal switching operation Heavy load PFM Boost in power save operation Light load 8.4.1 PWM Mode The TPS61230A typically operates at a quasi-constant 1.15 MHz frequency pulse width modulation (PWM) at moderate to heavy load currents. 8.4.2 PFM Mode The device integrates a power save mode with the pulse frequency modulation (PFM) to improve the efficiency at the light load. In the PFM mode, the device starts to switch when the output voltage trips below a set threshold voltage. When the output voltage ramping over the PFM threshold, the device stops switching. The DC output voltage in PFM mode rises above the nominal output voltage in PWM mode by 1.2%. Figure 14. Output Voltage in PFM / PWM Mode |
