TEA1738T datasheet

 

Description

The TEA1738, TEA1738T, TEA1738LT are a low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. The TEA1738(L) operates in peak current and frequency control mode. Frequency jitter has been implemented to reduce ElectroMagnetic Interference (EMI). Slope compensation is integrated for Continuous Conduction Mode (CCM) operation.

The TEA1738(L) IC includes OverPower Protection (OPP). This enables the controller to operate under overpower situationsfor a limited amount of time. Two pins, VINSENSE and PROTECT, are reserved for protection purposes. Input UnderVoltage Protection (UVP), output OverVoltage Protection (OVP) and OverTemperature Protection (OTP) can be implemented using a minimal number of external components.

Features

1. SMPS controller IC enabling low-cost applications

2. Large input voltage range (12 V to 30 V)

3. Integrated OverVoltage Protection (OVP) on pin VCC

4. Very low supply current during start-up and restart (10 μA typical)

5. Low supply current during normal operation (0.55 mA typical without load)

The IT8728F is a highly integrated Super I/O using the LowPin Count Interface. It provides the most commonly used legacy Super I/O functionality plus the latest Environment Control initiatives, including H/W Monitor and Fan Speed Controller. The device’s LPC interface complies with Intel “LPC Interface Specification Rev. 1.1”. The IT8728F is ACPI & LANDesk compliant.

The IT8728F features an enhanced hardware monitor providing three thermal inputs from remote thermal resistors, or thermal diode or diode-connected transistor (2N3904/2N3906). The device employs ITE’s innovative intelligent automatic Fan ON/OFF & speed control functions (SmartGuardian)to protect the system while reducing the system noise and power consumption.The Fan Speed Controller can control up to five fan speeds through five separate 256 steps of Pulse Width Modulation (PWM) output pins and monitor up to five FANs’ Tachometer inputs.
