Product Overview
LT8310 is a simple-to-use resonant reset forward converter controller that drives the gate of a low side N-channel MOSFET from an internally regulated 10V supply. It features duty mode control that generates a stable, regulated, isolated output using a single power transformer. With the addition of output voltage feedback, via opto-coupler (isolated) or directly wired (no isolated), current mode regulation is activated, improving output accuracy and load response. The flexibility to choose transformer turns ratio makes high step-down or step-up ratios possible without operating at duty cycle extremes. User programmable protection features include monitors on input voltage (UVLO and OVLO) and switch current (overcurrent limit). This device soft-start feature helps to protect the transformer from flux saturation. It is used in applications such as industrial, automotive and military systems, 48V telecommunication isolated power supplies, isolated and non-isolated DC/DC converters etc.
- Input voltage range is 6V to 100V
- High efficiency synchronous control
- Short-circuit (hiccup mode) overcurrent protection
- Synchronizable to an external clock
- Positive or negative polarity output voltage feedback with a single FBX pin
- Programmable soft-start, VIN operating current is 3.8mA typ at (TA = 25°C, VIN = 24V)
- Switching frequency is 100KHz typical at (RT = 100K to GND, VSS ≥ 2.9V, TA = 25°C, VIN = 24V)
- Operating input voltage is 6V to 100V
- VIN supply current in shutdown is 1µA maximum at (UVLO = 0V, TA = 25°C, VIN = 24V)
- Operating junction temperature is -40°C to 125°C, package style is 20-lead plastic TSSOP
