APW8716A
High Input Voltage 12A PWM Converter With Adjustable Soft Start
Features
General Description
Adjustable Output Voltage from +0.8V to +12V
- 0.8V Reference Voltage
- +1% Accuracy over Temperature
The APW8716A is a 12A, synchronous, step-down con-
verter with integrated 9.7mN-channel High-Side
MOSFET and 5.2mLow-Side MOSFET. The APW8716A
Operates from An Input Battery Voltage Range of steps down high voltage to generate low-voltage chipset
+2.7V to +28V
or RAM supplies in notebook computers.
20mA Low Dropout Regulator (LDO) with Fixed 5V The APW8716A provides excellent transient response and
Output
accurate DC voltage output in either PFM or PWM Mode.
Power-On-Reset Monitoring on LDO pin
In Pulse Frequency Mode (PFM), the APW8716A provides
Excellent line and load transient responses
very high efficiency over light to heavy loads with loading-
modulated switching frequencies. In PWM Mode, the con-
PFM mode for increased light load efficiency
verter works nearly at constant frequency for low-noise
Programmable PWM Frequency from 300kHz to requirements.
1000kHz
The APW8716A is equipped with accurate current-limit,
Integrated 9.7mat LDO=5V N-Channel MOSFET output under-voltage, and output over-voltage protections,
For High Side
perfect for various applications. A Power-On-Reset func-
Integrated 5.2mat LDO=5V N-Channel MOSFET tion monitors the voltage on LDO to prevent wrong
For Low Side
operation during power-on. The APW8716A has external
Integrated Bootstrap Forward P-CH MOSFET
adjustable soft-start and built-in an integrated output dis-
External Adjustable Soft-Start and Soft-Stop
charge method for soft stop. A soft-start ramps up the
output voltage with programmable timing to reduce the
Selectable Forced PWM or automatic PFM/PWM start-up current. A soft-stop function actively discharges
mode
the output capacitors.
Power Good Monitoring
The APW8716A is available in TQFN5x5-30 (Power PAK).
70% Under-Voltage Protection
125% Over-Voltage Protection
Current-Limit Protection

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines Greento mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
