Adding to its point of load (POL) family, these modules have been developed for system designers looking for compact, fully integrated, and easy-to-design POL products. They primarily address space and thermally constrained applications, telecom and datacom applications, servers, and network storage.
The TDM3883 and 3885 IPOL are fully integrated single-output buck converters, offering a high-efficiency continuous 3A/4A load capability and line regulation over a wide input supply range (4.5 – 14 V).
The integrated inductor and capacitors reduce external components and allow easier designs with much higher power density and deliver improved performance compared to discrete solutions due to the low parasitic parameters by minimising the PCB wiring trace needed.
Due to their tiny package size, the modules can fit into restricted PCB spaces offering up to a 80 percent area saving on the customer solution.
Both modules feature a low supply current (10 μA) at shutdown resulting in longer battery life for portable applications. Also, due to their tight reference voltage V REF tolerance (0.5 V±1.0 percent) and low ripple, they provide accurate power delivery and contribute to system stability and reliability. They also employ an Enhanced Stability COT (constant on time) engine with ceramic capacitors without external compensation as well as a forced continuous conduction mode (FCCM) option.
In addition, the modules come with thermally-compensated internal over-current protection (OCP), enhanced light load efficiency with reduced switching frequency and diode emulation mode (DEM). With ultra-light loads, they can enter a low quiescent current mode making it ideal for standby power supplies. Other features include internal soft-start, enable input, pre-bias start-up, thermal shut down, a power-good output, over-voltage protection (OVP), and UVLO.
The TDM3883 and TDM3885 modules with integrated inductor are available in a 2.7x3.1x2.3 mm 3 PG-LGA-15-1 package and a 3.1x3.8x2.3 mm 3 PG-LGA-15-2, respectively.
