1 MCP16301/H. High-Voltage Input Integrated Switch Step-Down Regulator Features General Description Up to 96% Typical Efficiency The MCP16301/H devices are highly integrated, Input Voltage Range: high-efficiency, fixed-frequency, step-down DC-DC. - to 30V (MCP16301) converters in a popular 6-pin SOT-23 package that operates from input voltage sources up to 36V. - to 36V ( mcp16301h ). Integrated features include a high-side switch, Output Voltage Range: to 15V fixed-frequency peak current mode control, internal 2% Output Voltage Accuracy compensation, peak current limit and overtemperature Qualification: AEC-Q100 Rev G, Grade 1 protection. Minimal external components are (-40 C to +125 C) necessary to develop a complete step-down DC-DC. Integrated N-Channel Buck Switch: 460 m converter power supply.

2 Minimum 600 mA Output Current Over All Input High converter efficiency is achieved by integrating the Voltage Range (See Figure 2-6 for Maximum current-limited, low-resistance, high-speed N-Channel Output Current vs. VIN): MOSFET and associated drive circuitry. High - up to 1A output current at , 5V and 12V switching frequency minimizes the size of external VOUT, SOT-23 package at +25 C ambient filtering components, resulting in a small solution size. temperature The MCP16301/H devices can supply 600 mA of 500 kHz Fixed Frequency continuous current while regulating the output voltage Adjustable Output Voltage from to 15V. An integrated, high-performance Low Device Shutdown Current peak current mode architecture keeps the output Peak Current Mode Control voltage tightly regulated, even during input voltage Internal Compensation steps and output current transient conditions that are common in power systems.

While turned off, only a few micro amps of current are Cycle-by-Cycle Peak Current Limit consumed from the input for power shedding and load Undervoltage Lockout (UVLO): distribution applications. Overtemperature Protection Output voltage is set with an external resistor divider. Available Package: SOT-23-6 The MCP16301/H devices are offered in a space-saving SOT-23-6 surface mount package.
