Switch Mode Power Supply with Multiple Linear Regulators The 33730 is a multiple output power supply integrated circuit for automotive applications. The integrated circuit (IC) incorporates a switching regulator which operates over a wide input voltage range from +4.5V to +26.5V. The step-down switching regulator uses a fixed frequency PWM voltage mode control. It has a 3.5A current limit (typical) and the slew- rate is adjustable via a control pin to reduce switching noise. The switching regulator has an adjustable frequency oscillator, which allows the user to optimize its operation over a wide range of input voltages and component values. The linear regulators can be configured either as two normal mode regulators (VDD3, VDDL) and one standby regulator (VKAM), or as one normal mode linear regulator (VDDL) and two standby regulators (VKAM and VDD3 Standby). Two protected outputs [VREF (1, 2)] are used to provide power to external sensors. Features • Provides all regulated voltages for Freescale 32-bit microcontroller family • Adjustable frequency switching buck regulator with slew-rate control • Power sequencing provided • Programmable voltages VDDL, VDD3 - 3% accuracy • Programmable standby regulator VKAM - 15% accuracy, operating down to 4.5V at KA_VBAT pin •VDD3 can be programmed as an optional second standby regulator with 15% accuracy • Provides two 5.0V protected supplies for sensors • Provides reverse battery protection FET gate drive • Provides necessary MCU monitoring and fail-safe support • Pb-free packaging designated by suffix code EK Figure 1. 33730 Simplified Application Diagram SWITCHING POWER SUPPLY EK SUFFIX (PB-FREE) 98ARL10543D 32-LEAD SOICW-EP 33730 ORDERING INFORMATION Device Temperature Range (TA) Package MCZ33730EK/R2 -40°C to 125°C 32-SOICW-EP VBAT KA_VBAT VIGN VREF1,2 GND HRT BOOT SW VDDH VCOMP VDD3_B VDD3 VDDL VKAM RSTs + + 5.0 V + + INV VDDL_B 5.0V KA_1.0V 1.5V MCU (32 Bit) 3.3V 33730 P1 P2 PFD P3 REGON IGN_ON CP 5.0V |
