Details
General DescriptionThe APW7088, two-phase PWM control IC, provides a precision voltage regulation system for advanced graphic microprocessors in graphics card applications. The integration of power MOSFET drivers into the controller IC reduces the number of external parts for a cost and space saving power management solution.The APW7088 uses a voltage-mode PWM architecture, operating with fixed-frequency, to provides excellent load transient response. The device uses the voltage across the DCRs of the inductors for current sensing. Load line voltage positioning (DROOP), channel-current balance and over-current protection are accomplished through continuous inductor DCR current sensing.Features· Voltage-Mode Operation with Current Sharing - Adjustable Feedback Compensation - Fast Load Transient Response· Operate with 8V~13.2VCC Supply Voltage· Programmable 3-Bit DAC Reference -±1.5% System Accuracy Over Temperature· Support Single- and Two-Phase Operations· 5V Linear Regulator Output on 5VCC· 8~12V Gate Drivers with Internal Bootstrap Diode· Lossless Inductor DCR Current Sensing· Fixed 300kHz Operating Frequency Per Phase· Power-OK Indicator Output- Regulated 1.5V on POK· Adjustable Over-Current Protection (OCP)· Accurate Load Line (DROOP) Programming· Adjustable Soft-Start· Over-Voltage Protection (OVP)· Under-Voltage Protection (UVP)· Over-Temperature Protection (OTP)· QFN4x4 24-Lead Package (QFN4x4-24)· Lead Free and Green Devices Available (RoHS Compliant)Applications· Graphics Card GPU Core Power Supply· Motherboard Chipset or DDR SDRAM Core Power Supply· On-Board High Power PWM Converter with Out put Current up to 60A
