MAX15569
2-Phase/1-Phase QuickTune-PWM Controller with
Serial I²C Interface
Electrical Characteristics (0°C to +85°C) (continued)
(Circuit of Figure 1. V_IN = 10V, V_BIAS = 5V, V_TT = 1.8V, EN = BIAS, GNDS = AGND, V_FBAC = V_FB = V_{CSP_} = V_{CSN_} = 1V [SETVOUT
register 0x07h set to 0x33h]. T_A = 0°C to +85°C, unless otherwise noted. Typical values are at +25°C. All devices 100% tested at
+25°C. Limits over temperature are guaranteed by design.)
