ZHCSK64B October 2019 – December 2020 TPSM265R1
PRODUCTION DATA
The TPSM265R1 operates in Pulse Frequency Modulation (PFM) mode. The TPSM265R1 behaves as a hysteretic voltage regulator operating within upper and lower feedback regulation thresholds with typical 10 mV of hysteresis. Figure 7-4 is a representation of the relevant voltage waveforms and inductor current waveform. The TPSM265R1 provides the required switching pulses to recharge the output capacitance, followed by a sleep period where most of the internal circuits are shut off. The load current is supported by the output capacitor during this time, and the TPSM265R1 current consumption approaches the sleep quiescent current of 10.5 μA (typ). The sleep period duration depends on load current and output capacitance.
