60V, 500mA, Ultra-Small, High-Efficiency,
Synchronous Step-Down DC-DC Converter
ELECTRICAL CHARACTERISTICS (continued)
(V_IN = 24V, V_GND = V_PGND = 0V, C_VIN = C_VCC = 1FF, V_EN = 1.5V, C_SS = 3300pF, V_FB = 0.98 x V_OUT, LX = unconnected, RESET =
unconnected. T_A = T_J = -40NC to +125NC, unless otherwise noted. Typical values are at T_A = +25NC. All voltages are referenced to GND,
unless otherwise noted.) (Note 2)
