Wide Vin range, 3A Buck Module with integrated
passives suitable for industrial applications
Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL) a
designer, developer, and global supplier of a broad range of power
semiconductors, power ICs, and digital power products today
announced the release of the AOZ29303QI, a simple-to-use highly
integrated buck module. The product is available in a 9mm x 6mm QFN
48-lead exposed pad package with a 3.7mm height. AOZ29303QI can
deliver an output current of 3A with input voltage up to 30V and
output voltage up to 5.5V. The new device offers a simple, compact
solution suited to a wide variety of applications such as
industrial, factory automation, networking, and general-purpose
point of load.

The buck module comprises a controller IC, power MOSFET,
rectifier diode, bootstrap capacitor, and an inductor. It can
achieve up to 93% peak efficiency. When operating in low output
current conditions, the device will run in a proprietary pulse
energy mode (PEM) to achieve high efficiency by reducing switching
loss. Under this mode, the regulators can still maintain 85%
efficiency in 10mA light load operation making it an ideal choice
for “always on” applications.
A suite of operation protections is available for this
integrated module: cycle-by-cycle Over-Current Protection (OCP),
output Over-Voltage Protection (OVP), output Short-Circuit
Protection (SCP), and Over-Temperature Protection (OTP). External
components required to realize a complete solution are minimal and
offer the user flexibility to choose soft-start time, operating
frequency, external compensation, and output voltage setting.
“AOS’ first module is based on our AOZ128x family of regulators
that has been adopted in a range of industrial applications such as
factory automation, automated meter reading for its ease of use and
wide operating range,” said Peter Cheng, Power IC Senior Marketing
Director at AOS. “By offering a module option, AOS’ intention is to
offer system designers an even simpler implementation, speeding
time to market and improving solution size.”
