3.3 V/20 A Electrical Specification
PKB 4610 PINB
T_ref = -40 to +90ºC, V_I = 36 to 75 V, sense pins connected to output pins unless otherwise specified under Conditions.
Typical values given at: T_ref = +25°C, V_I= 53 V_I max I_O, unless otherwise specified under Conditions.
Additional C_in = 0 μF and C_out = 0 μF. See Operating Information section for selection of capacitor types.
