TD8588
TD8588 is 1.2MHz Synchronous Boost Converter manufactured by Techcode.
Description
Features
The TD8588 is a synchronous rectifier, fixed switching frequency (1.2MHz typical), and current‐mode step‐up regulator. The device allows use of small inductors and output capacitors for USB devices. The current‐mode control scheme provides fast transient response and good output voltage accuracy. At light loads, the TD8588 will automatically enter in Pulse Frequency Modulation (PFM) operation to reduce the dominant switching losses. During PFM operation,the IC consumes very low quiescent current and maintains high efficiency over the plete load range.The TD8588 also includes current‐limit and overtemperature shutdown to prevent damage in the event of an output overload. The TD8588 is available in ESOP‐8 packages.
