Note 1: All devices are 100% tested at TA = +85°C. All limits over temperature are guaranteed by characterization.
Note 2: VREF is measured with FB connected to the COMP pin (see Functional Diagram).
Note 3: The MAX5052 is intended for use in universal input power supplies. The internal clamp circuit is used to prevent the boot-
strap capacitor (C1 in Figure 1) from charging to a voltage beyond the absolute maximum rating of the device when
EN/UVLO is low. The maximum current to VIN (hence to clamp) when UVLO is low (device in shutdown) must be externally
limited to 2mA, max. Clamp currents higher than 2mA may result in clamp voltage higher than 30V, thus exceeding the
absolute maximum rating for VIN. For the MAX5053, do not exceed the 24V maximum operating voltage of the device.
ELECTRICAL CHARACTERISTICS (continued)
(VIN = +12V (for MAX5052, VIN must first be brought up to 23.6V for startup), 10nF bypass capacitors at VIN and VCC, CNDRV = 0,
VUVLO = +1.4V, VFB = +1.0V, VCOMP = floating, VCS = 0V, typical values are measured at TA = +25°C, TA = -40°C to + 85°C, unless
otherwise noted.) (Note 1)
