... ADJUSTABLE DC-DC BOOST CONVERTER WITH INTERNAL SWITCH IN TSOT23-5 DESCRIPTION The ZXLD1615 is a PFM inductive boost converter designed to provide output voltages 28V from a 2.5V to 5.5V input supply. The ZXLD1615 includes the output switch and peak current sense resistor, and can provide up to 10mA output current at maximum output voltage ...

... The output during this mode of operation will voltage equal to V REF cycle. Gated PWM operation The internal circuitry of the ZXLD1615 is turned off when no signal is present on the 'EN' pin for more than 120 s (nominal). A low frequency signal applied to the EN pin will therefore gate the device 'on' and *(R1+R2)/R1. ...

... Square wave signals applied to the EN pin, for example, will turn the device on and produce a nominal regulated output of 13.5V. The ZXLD1615 contains a timing circuit that switches the device on a few microseconds after the application of a rising edge to EN and turns it back off again nominally 120µs after the falling edge ...
