Price Comparison for MAX13253ATB+T
Series Information for MAX13253ATB+T - Maxim Integrated


The MAX13253 is a 1A, push-pull, transformer driver designed to provide a simple solution for low-EMI isolated power supplies. The MAX13253 has an internal oscillator and operates from a single +3.0V to +5.5V supply. The transformer’s secondary-to-primary winding ratio defines the output voltage, allowing selection of virtually any iso- lated output voltage with galvanic isolation. The MAX13253 features an integrated oscillator driving a pair of n-channel power switches. The driver includes pin-selectable spread-spectrum oscillation and a well- controlled slew rate to reduce EMI. The MAX13253 can optionally be driven by an external clock to further man- age EMI. Internal circuitry guarantees a fixed 50% duty cycle to prevent DC current flow through the transformer, regardless of which clock source is used. The MAX13253 operates with up to 1A of continuous current and features integrated protection including fault detection, overcurrent protection, and thermal shutdown. The MAX13253 includes a low-current shutdown mode to reduce the overall supply current to less than 5µA (max) when the driver is disabled. The MAX13253 is available in a small 10-pin (3mm x 3mm) TDFN package and is specified over the -40°C to +125°C temperature range.
