Next Generation Single & Dual Output 1W SMD DC-DC Converters
Replacing the ISE/ISA series, the surface mount single output IES01 and dual output IAS01 of un-regulated converters include a new integrated controller chip, resulting in a lower component count that provides an enhanced yield with cost savings. Other benefits are: better capacitive loading characteristics; integrated over temperature and short circuit protection; higher efficiency at light load and no-load reducing power consumption.
The input range is +/-10%: 4.5 to 5.5VDC for 5.0 Volt nominal. The IES01 has six single output voltages: 3.3, 5.0, 9.0, 12, 15 & 24VDC. The IAS01 has five dual output voltages: ±5.0, ±9.0, ±12, ±15 & ±24VDC, the ±15 & ±24 could be used to provide single output voltages of 30 & 48VDC.
There is a minimum load requirement of 10%, efficiency is up to 85%. The input to output isolation is 1.5kVDC, if required a 3.0kVDC isolation version can be ordered by adding a -H suffix to the part number.
These 1 watt convection cooled converters have a wide operating temperature range of -40°C to +105°C with full power available to +100°C. Standards include: Safety IEC/EN/UL62368-1; EMC immunity EN61000-4-2 for ESD; EN55032 Class B for conducted EMC emissions (with minimal additional components). Moisture sensitivity level (MSL) = 1. Protection category: IPX6 according to IEC60529. Meantime between failure is 3.5Mhrs at 25°C (MIL-HDBK-21F).
The single output IES01 is housed in a DIP8 SMD package which measures 0.52” x 0.335” x 0.285” (13.2 x 8.5 x 7.25mm) and is supplied in tube quantities of 38. The dual output IAS01 is housed in a DIP10 SMD package which measures 0.60” x 0.335” x 0.285” (15.24 x 8.5 x 7.25mm) and is supplied in tube quantities of 32. There is an option to supply on tape & reel for volume production by adding suffix -TR to the part number, reel quantity = 500.
The IES01/IAS01 provide excellent cost savings, whilst offering an enhanced specification compared to the original ISE/ISA series. The improved efficiency and reduced power consumption will particularly benefit battery powered applications by providing a longer battery life. With an IPX6 rating, the devices are suitable for production processes utilizing water wash cleaning.
