14 / 118 page  NXP Semiconductors FS5600 Automotive buck regulator and controller with voltage monitors and watchdog timer 11 SW1: 36 V integrated FET DC-DC converter SW1 is a 3 A integrated FET DC DC converter. Load currents of up to 3.5 A may be drawn without entering current limit. Figure 6 shows a high-level block diagram of SW1. aaa-037154 SW1BOOT SW1LX SW1IN EN1 CONTROL, DRIVER AND LOGIC Q1 Q2 VCC SW1FB PGND (EPAD) SW1LX Figure 6. SW1 high-level block diagram SW1IN pins provide input power to the MOSFETs, and VCC provides the voltage needed to drive the MOSFET gates. EN1 controls the enable of the SW1 regulator. 11.1 SW1 electrical specifications All parameters are specified at Tj = –40 °C to 150 °C, VSW1IN = 6 V to 18 V, Vout = 5 V, typical external component values, unless otherwise noted. Typical parameters are specified at VSW1IN = 12 V, Tj = 25 °C unless otherwise noted. Parameter Symbol Min Typical Max Units Output Voltage Accuracy (PWM mode, SW1IN = 6 V to 18 V, 0 A <= ISW <= Rated A, minimum 2 V headroom, Vout = 1.8 V to 5.5 V using internal resistor divider) VSW1ACC –2 — 2 % Output Voltage Accuracy in Dropout: (PWM mode, SW1IN = 6 V to (Vout+2 V), 0 A <=ISW <= Rated A, 25C, Vout <= 5 V, 450 kHz) VSW1ACCDO -3 — 3 % Output Voltage Accuracy (Internal resistor divider, PFM mode, Load = 10 mA) VSW1ACC –3 — 3 % Reference accuracy when using external resistor divider VSW1ACC 0.99 1 1.01 V Rated load current (PWM mode) VSW1LOAD 3 — — A Soft-start time (all output voltages) (Measured from 0 % to 90 % of Vout) OTP_SW1_SS = 00 OTP_SW1_SS = 01 OTP_SW1_SS = 10 OTP_SW1_SS = 11 tss — 337 675 1350 2700 500 1000 2000 4000 us Operating frequency range (selectable via OTP) SW1FSW 250 — 3000 kHz Table 8.
