ONNCP3063DR2G
Overview
The NCP3063DR2G is a versatile monolithic switching regulator capable of buck, boost, and inverting configurations. It operates at a fixed frequency of 150kHz and features an internal 1.5A switch, making it a robust choice for DC-DC conversion up to 40V. The device is designed to be a higher-frequency, modernized upgrade to the industry-standard 34063 series.
Why Choose This Part
This regulator simplifies design by supporting multiple topologies (positive or negative output) with a wide input range up to 40V. It includes integrated safety features like cycle-by-cycle current limiting and thermal shutdown with hysteresis. The 150kHz switching frequency allows for the use of smaller inductors and capacitors compared to older 100kHz alternatives.
Applications
Key Specifications
Getting Started
To begin design, calculate the external timing capacitor (CT) value to set the internal oscillator and select the sense resistor (Rsc) for the desired current limit. Refer to the datasheet application circuits for component values specific to buck, boost, or inverting modes. Evaluation can be performed using generic SOIC-8 breakout boards or custom PCB layouts following the recommended grounding practices to minimize switching noise.
