RAA210030

5V, 3A Step-Down DC/DC Mini Module with Integrated Inductor

The RAA210030 power module is a compact,

Features

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.

▪ 3A complete power supply

• Integrates controller, gate driver, MOSFETs, and

inductor

▪ 2.7V to 5.5V input voltage range

▪ Adjustable output voltage

• As low as 0.6V with ±1.5% accuracy over line,

load, and temperature

Based on a peak current mode control scheme, the

RAA210030 provides 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.

• Up to 95% efficiency

▪ Default 2MHz current mode control operation

• 500kHz to 4MHz resistor adjustable

• External synchronization up to 4MHz

• 100% duty cycle

▪ Dedicated enable pin and power-good flag

▪ Internal 1ms soft-start time

▪ Selectable PFM or FPWM mode

▪ Soft-stop output discharge

▪ UVLO, OCP, negative OCP, OVP, and OTP

• OCP/Short-Circuit Protection (SCP) hiccup

mode

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.

▪ Compact RoHS compliant 3mm×3mm×1.08mm

(1.15mm Max) 10 lead dual flat embedded

laminate package

Applications

▪ Telecom, Industrial, optical, and medical equipment

An array of protection features, including input

Undervoltage Lockout (UVLO), Overcurrent

Protection (OCP), output Overvoltage Protection

(OVP), and Over-Temperature Protection (OTP),

ensures safe operations under abnormal operating

conditions.

▪ Point-of-load conversions

▪ MCU, MPU, DSP, and FPGA

The RAA210030 is available in a compact RoHS

compliant 3mm×3mm×1.08mm (1.15mm MAX) dual

flat embedded laminate package.
