PART NUMBER:
VPOL5A-5-SMT
DESCRIPTION:
point of load converter
features
* high efficiency topology, typically 94% at
3.3 Vdc
* industry standard footprint
* wide ambient temperature range, -40C to
+85C
* cost efficient open frame design
* programmable output voltage via external
resistor from 0.75 to 3.63 Vdc
* no minimum load requirement (stable at all
loads)
* remote on/off
* remote sense compensation
* fixed switching frequency
* continuous short-circuit protection and over
current protection
* over-temperature protection (OTP)
* monotonic startup with pre-bias at the output.
* UL/IEC/EN60950-1 (E222736) certified.
