Power Controller IC targets automotive applications.
Press Release Summary:
April 11, 2012 - Dual output power supply, TPS43330-Q1 series, ensures stable and uninterrupted output voltages, even when input voltage drops significantly below output voltage levels such as with instances involving car's start/stop function. Input range of 2-40 V and transients up to 60 V ensure continued operation, while spread spectrum frequency modulation reduces conducted EMI. Along with multiple voltage rails and voltage supervisors, series integrates dedicated high-side FET driver.

TI Unveils Integrated Power Controller for Automotive Applications
Press release date: April 2, 2012
Key features and benefits of the TPS43330-Q1 family:
-- Wide input voltage range of 2 V to 40 V and transients up to 60 V ensure continued operation, even under severe battery voltage conditions. -- Ultra-low quiescent current as low as 35 uA and lower shutdown current of 5 uA reduces the overall application power consumption from the battery in standby operation, extending battery lifetime and eliminating the need for a standby voltage regulator. -- Spread spectrum frequency modulation reduces conducted electromagnetic interference and allows for simpler, lower-cost filters. -- Individual enable and power good signals for both supply rails allow the customer flexible power sequencing based on specific application needs. -- Integration of multiple voltage rails and voltage supervisors reduces board space, design complexity and system cost compared to a discrete solution. -- Dedicated high-side FET driver enables overall efficiency improvement by bypassing the external reverse-battery protection diode with an external PMOS FET.
Tools and support
TI offers a variety of tools and support to speed design with the Power Stage Designer and Automotive Power reference design for PMP7001.1 and PMP7031. Evaluation modules are also available for the TPS43332-Q1, TPS43335-Q1, and TPS43336-Q1 devices.
In addition to the TPS43330-Q1 DC/DC controller, TI offers a large portfolio of power management ICs aimed at automobile applications, including step-down converters like the TPS57160-Q1 or PIMCs like the TPS65023-Q1. The LM25118Q buck-boost controller and TPIC74101-Q1 buck-boost converter help maintain stable output voltage over a wide supply voltage range.
Availability, packaging and pricing
Samples of the TPS43330-Q1 and TPS43332-Q1 are available now in an HTSSOP-38 (DAP) package. Suggested retail pricing for the TPS43330-Q1 family ranges from US $2.85 to $3.10 in 1000-unit quantities.
