5V, 3A Step-Down DC/DC Low Profile Mini Module with Integrated Inductor
ページセクションへ移動：
概要
説明
The RAA210030 power module is a compact, single-channel, synchronous step-down, non-isolated complete power supply, capable of delivering up to 3A of continuous current. By operating from a single 2.7V to 5.5V input power rail and integrating the controller, gate driver, power inductor, and MOSFETs, the RAA210030 is optimized for space-constrained applications.
Based on a peak current mode control scheme, the RAA210030 provides a fast transient response and excellent loop stability. The output voltage can be set as low as 0.6V, with setpoint accuracy better than ±1.5% over line, load, and temperature. The operating frequency has a 2MHz default setting, however it can also be set from 500kHz to 4MHz by an external resistor. The external synchronization is also supported with an external clock signal up to 4MHz. The RAA210030 supports 100% duty cycle operation to minimize switching losses with typically 300mV dropout voltage. A dedicated enable pin and power-good flag allow for easy system power rails sequencing.
The RAA210030 can be configured for pulsed frequency modulation (PFM) or forced pulse width modulation (FPWM) at light load. FPWM reduces noise and RF interference, while PFM provides higher efficiency by reducing switching losses at light loads.
