... Input Voltage [V] © 2006 Semtech Corp. current, and then changes to 32kHz when there is no load current. This is done to save battery power by taking ad- vantage of the lower 280μA quiescent current at 32kHz. The ripple voltage seen at the output is reasonable for LED applications, but the output capacitance can be in- creased to reduce the ripple if required ...

... Semtech Corp. Ripple Performance Examples of the output ripple, charge pump frequency and capacitor size are listed in Table 2. Switch mode regulators have harmonics which vary due to the pulse width modulation used to regulate the output. Varying harmonics can make it diffi cult to ensure accept- able noise performance over the entire operating range ...

... Ro can be measured to verify a low transition imped- ance. Before measuring Ro, select the capacitors, set the operating frequency and a constant load current. Find the input voltage just before a weak to strong mode tran- sition (i.e., 1. mode). Measure V before the transition. Ro will be, mode V IN Ro= I OUT © 2006 Semtech Corp ...
