Torex Semiconductor has added a new package of height 0.315mmto theXC6216 series of 28V operating voltage regulators with a standby function.
IC cards (smart cards) have become common in recent years, and are being used for official documents (licenses, passports, ID cards), access control (employee ID cards, student ID cards, secret area access), medical cards (health insurance cards, consultation tickets), payment cards (credit cards, debit cards, bank cards), and information security (Internet transactions, data access control). The number of such cards issued continues to increase dramatically in many different fields.
The ISO/IEC 7810 international standard specifies the dimensions and thickness (54.98mm x 85.60mm x 0.760mm) of IC cards (smart cards). Cards with a display function have recently started to appear, and cards equipped with a Li-ion battery are becoming common. It is expected that this will increase the demand for voltage regulators, battery charger ICs, and other power supply ICs.
Considering the thickness of the flexible circuit board (0.07mm) and reinforcement plate used in the card, there is an increasing need for thin packages of height 0.4mm or less to house the power ICs and external components that are incorporated inside the card. Because the battery in the card has a small capacity, low power consumption is desirable, and for non-contact charging, a power supply IC that can operate at a voltage of 18V or higher is required.
Based on this background, we added the new ultra-low profile (1.8 x 1.5 x h0.315mm) USP-6B06 package to our existing XC6216 series, which features a high withstand voltage and low consumption. This new package is the thinnest-class in the industry and is an ideal product for the power specifications of smart cards. Torex will continue to develop products that meet market needs for small sizes and low profiles, and contribute to the realization of a richer and fuller society.
