Controller IC Chip - High-Performance Notebook PWM Controller MOSFET APW7138 APW 7138 chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0299)

The APW7138 is a single-phase, constant-on-time, and synchronous PWM controller which drives N-channel MOSFETs. The APW7138 steps down high voltage of a battery to generate low-voltage chipset or RAM supplies in notebook computers. The APW7138 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Modulation (PFM) Mode, the APW7138 provides very high efficiency over light load with loading-modulated switching frequencies. When the inductor current is continuous, the operation automatically enters PWM mode with relatively constant switching frequency. For QFN4x4-16A and TQFN3x3-16 packages, the Forced-PWM Mode works nearly at constant frequency for low-noise requirements. The APW7138 is equipped with accurate over-current, output under-voltage, and over-voltage protections per-fect for NB application. A Power-On-Reset function moni-tors the voltage on VCC pin to prevent errorneous opera-tion during power-on. The APW7138 has a digital soft-start and soft-stop. The internal integrated soft-start ramps up the output voltage with controlled slew rate to reduce the start-up current. The digital soft-stop function actively discharges the output capacitors with controlled reverse inductor current. The APW7138 is available in SSOP-16, QFN4x4-16A, and TQFN3x3-16 packages.

Adjustable Output Voltage from +0.6V to +3.3V - 0.6V Reference Voltage - °/0 Accuracy Over Temperature Operates from an Input Battery Voltage Range of +3V to +25V Wide Output Load Range from OA to 25A Power-On-Reset Monitoring on VCC Pin Excellent Line and Load Transient Response PFM Mode for Increased Light Load Efficiency Programmable PWM Frequency from 200kHz to 600kHz Integrated MOSFET Drivers and Bootstrap Diode Internal Integrated Soft-Start and Soft-Stop Selectable Forced PWM or Automatic PFM/PWM Mode (only for QFN4x4-16A and TQFN3x3-16 Packages) Power Good Monitoring Fault Identification by PGOOD Pull-Down Resistance 70% Under-Voltage Protection (UVP) 124% Over-Voltage Protection (OVP) Adjustable Over-Current Protection (OCP) - Sensing Low-Side MOSFET's Current Over-Temperature Protection (OTP) SSOP-16.
