SLVSHJ8 February 2024 TPS61299-Q1
PRODUCTION DATA
The TPS61299-Q1 boost converter does not have fixed frequency and it maintains a constant inductor ripple current in the range of 350mA, so the frequency is determined by the operation condition. The frequency is approximately 3MHz, the input is 3.6V, output is 5V, inductor is 1μH. Refer to to calculate the efficiency. The estimated switching frequency ƒ in continuous current mode can be calculated by Equation 1. The switching frequency is not a constant value, but is determined by induction, input voltage, and output voltage.
