Versatile 12A Buck Converter for Ultra-Compact PCB Layout

1 MHz Operation and High Integration in a 3mmx4mm QFN Package

Highly integrated SZPL8216A family of synchronous Point-of-Load (PoL) Buck Converters. These DC/DC buck converters integrate the functions of the DC/DC COT controller, output gate drivers and output power blocks all in one compact 3mmx4mm QFN package to deliver the best power density with a minimum external component count. The devices enable designers to achieve ultra-compact PCB layout, high power density and high efficiency for low power loss in demanding and space-constrained applications such as enterprise servers, telecommunications, and networking equipment.

Key Specs:

  • Ultra-Compact QFN 3mmx4mm Package

  • 94% Peak Efficiency

  • Up to 1 MHz Switching Frequency

  • 4.5V to 16V Input Voltage Range

  • 0.6V to 5.5V Output Voltage Range

Key Features:

  • Proprietary S-Loop    Control and Adaptive COT Architecture for Fast Load Transient Response

  • All Ceramic Output Capacitor Solution

  • Programmable Current Limit

  • Internal LDO for MOSFET Driver Bias

  • Output Tracking with External Reference Input

  • UVLO/OCP/OVP/UVP/OTP Protections

  • Pre-bias Startup with Programmable Soft Start Time

  • Diode Emulation Mode for Light Load Efficiency Boost



The SZPL8216A-A, SZPL8216A-B and SZPL8216A-C family of devices delivers up to 12 Amps with 94% peak efficiency when converting from a nominal 12V input down to a 0.6V to 5.5V output voltage range. Providing design versatility, the devices feature a selectable switching frequency, 600 kHz to 1 MHz, allowing users to make design-specific decisions to optimize their component size versus efficiency. With the ability to operate at 1 MHz, designers can use a smaller output filter to minimize their total PCB solution size.

The SZPL8216A COT controlled devices employ Silanna’s proprietary S-Loop Control Architecture which provides near instantaneous response to load transitions with minimal increase in overshoot or undershoot. Such performance is critical for multi-core CPU and FPGA applications that quickly power on and off with high current load transients and require a very stable power supply voltage.
