MCP16311/2 30V Input, 1A Output, High-Efficiency, Integrated Synchronous Switch Step-Down Regulator Features General Description • • • • • • The MCP16311/2 is a compact, high-efficiency, fixed frequency, synchronous step-down DC-DC converter in an 8-pin MSOP, or 2 x 3 mm TDFN package that operates from input voltage sources up to 30V. Integrated features include a high-side and a low-side switch, fixed frequency peak current mode control, internal compensation, peak current limit and overtemperature protection. The MCP16311/2 provides all the active functions for local DC-DC conversion, with fast transient response and accurate regulation. • • • • • • • • • • • Up to 95% Efficiency Input Voltage Range: 4.4V to 30V 1A Output Current Capability Output Voltage Range: 2.0V to 24V Passes Automotive AEC-Q100 Reliability Testing Integrated N-Channel High-Side and Low-Side Switches: - 170 m, Low Side - 300 m, High Side Stable Reference Voltage: 0.8V Automatic Pulse Frequency Modulation/PulseWidth Modulation (PFM/PWM) Operation (MCP16311): - PFM Operation Disabled (MCP16312) - PWM Operation: 500 kHz Low Device Shutdown Current: 3 µA Typical Low Device Quiescent Current: - 44 µA (Non-switching, PFM Mode) Internal Compensation Internal Soft-Start: 300 µs (EN Low-to-High) Peak Current Mode Control Cycle-by-Cycle Peak Current Limit Undervoltage Lockout (UVLO): - 4.1V typical to start - 3.6V typical to stop Overtemperature Protection Thermal Shutdown: - +150°C - +25°C Hysteresis Applications • • • • • • • • • • • • PIC®/dsPIC® Microcontroller Bias Supply 24V Industrial Input DC-DC Conversion General Purpose DC-DC Conversion Local Point of Load Regulation Automotive Battery Regulation Set-Top Boxes Cable Modems Wall Transformer Regulation Laptop Computers Networking Systems AC-DC Digital Control Bias Distributed Power Supplies  2013-2021 Microchip Technology Inc. and its subsidiaries High converter efficiency is achieved by integrating the current-limited, low-resistance, high-speed high-side and low-side switches and associated drive circuitry. The MCP16311 is capable of running in PFM/PWM mode. It switches in PFM mode for light load conditions and for large buck conversion ratios. This results in a higher efficiency over all load ranges. The MCP16312 runs in PWM-only mode, and is recommended for noise-sensitive applications. The MCP16311/2 can supply up to 1A of continuous current while regulating the output voltage from 2V to 12V. An integrated, high-performance peak current mode architecture keeps the output voltage tightly regulated, even during input voltage steps and output current transient conditions common in power systems. The EN input is used to turn the device on and off. While off, only a few micro amps of current are consumed from the input. Output voltage is set with an external resistor divider. The MCP16311/2 is offered in small MSOP-8 and 2 mm x 3 mm TDFN surface mount packages. Passes automotive AEC-Q100 reliability testing.
