APW8713B
High Input Voltage 8A PWM Converter With Adj. Soft Start
Features
General Description
Adjustable Output Voltage from +0.8V to +12V
The APW8713B is a 8A, synchronous, step-down con-
- 0.8V Reference Voltage
verter with integrated 30mN-channel High-Side
- +1% Accuracy over Temperature
MOSFET and 9mLow-Side MOSFET. The APW8713B
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 5. The APW8713B provides excellent transient response and
3V Output
Power-On-Reset Monitoring on LDO pin
Excellent line and load transient responses
accurate DC voltage output in either PFM or PWM Mode.
In Pulse Frequency Mode (PFM), the APW8713B provides
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 100kHz to requirements.
1000kHz
The APW8713B is equipped with accurate current-limit,
Integrated 30mat 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 9mat LDO=5V N-Channel MOSFET For tion monitors the voltage on VLDO to prevent wrong
Low Side
operation during power-on. The APW8713B has external
Integrated Bootstrap Forward P-CH MOSFET
adjustable soft-start and built-in an integrated output dis-
charge method for soft stop. A soft-start ramps up the
External Adjustable Soft-Start and Soft-Stop
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 APW8713B is available in TQFN4x4-23 (Power PAK).
70% Under-Voltage Protection
125% Over-Voltage Protection
Current-Limit Protection
Applications
- Using Sense Low-Side MOSFETs RDS(ON)
Over-Temperature 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).
