DataSheeT enpirion power solutions EN29A0QI 10A Power Module Step-Down DC-DC Switching Converter with Integrated Inductor DESCRIPTION FEATURES The EN29A0QI is a member of the EN2900 family of Very low noise and ripple for transceiver power PowerSoCs optimized for powering noise sensitive High accuracy VREF: 1% over Line, Load, Temp loads which require tight DC and AC tolerance such as Remote ground sense for tight POL regulation transceiver, high speed IO, and RF. PowerSoC devices Optimized for powering VCCR, VCCT, and VCCH integrate the controller, MOSFETS, inductor, and high High efficiency V =12V, V =1.0V 86.5% 10A frequency bypass capacitors to provide a low noise, IN OUT low ripple, easy to use power conversion solution. 10A continuous output current with no derating Wide input voltage range (9V to 16V) The EN29A0QI offers very tight DC accuracy combined with remote ground sense to meet the Bidirectional frequency synchronization challenging tolerance requirements for high speed High performance error amplifier transceivers. The inductor is sized to provide very low Precision enable and POK for sequencing output switching ripple while the package is designed Programmable soft-start and soft-shutdown for low EMI. The loop topology is based on low Full suite of protections: OCP, SCP, OTP, Input impedance voltage mode control combined with a OVLO, UVLO, Output OVP with programmable high-performance error amplifier for excellent threshold transient performance. The wide bandwidth loop, combined with the low impedance voltage mode Monotonic startup into pre-biased loads control can enable a significant reduction of RoHS compliant, MSL level 3, 260C reflow expensive bulk decoupling capacitors. APPLICATIONS The EN29A0QI features a bidirectional SYNC pin Noise sensitive FPGA rails such as transceiver and which enables synchronization from an external high-speed IO clock, or can provide a master clock output. Other features include precision enable threshold, glitch Sensitive RF applications such as RRU free startup into a pre-biased load, and Wireless and Wireline communications systems programmable soft-start and soft-shutdown.
