APW8733

APW8733 Dual-Phase COT Buck PWM Controller with Dynamic Voltage Features General Description High Input Battery Voltages Range from 1.8V to The APW8733 is a dual-phase PWM control IC which 25V Input Power provides a precision voltage regulation system for ad- Multiform Purpose Input Voltage Collocation: VCC vanced graphic card and motherboard applications. The = 5V / VIN = 5.5V ~ 19V for NB MXM application integration of dual-phase power MOSFET drivers into the Built in VREF voltage = 2.0V +1% with all controller IC and reduces the number of external parts for temperature range a cost and space saving power management solution. External reference input with PWM VID Dynamic The APW8733 uses a constant on time architecture voltage control control, and results in excellent transient response and Integrated Bootstrap Forward P-CH MOSFET accurate DC voltage output in either PFM or PWM Mode. Built in Adjustable Frequency by TON : 100KHz ~ In Pulse Fre...
