150KHz, 3A PWM Buck DC/DC Converter

Function Descriptions

Pin Functions

Vcc

This is the positive input supply for the IC switching regulator. A suitable input

bypass capacitor must be presented at this pin to minimize voltage transients and to

supply the switching currents needed by the regulator.

Vss

Circuit ground.

Internal switch. The voltage at this pin switches between (+V_CC– V_SAT) and

approximately – 0.5V, with a duty cycle of approximately V_OUT/ V_CC. To minimize

coupling to sensitive circuitry, the PC board copper area connected to this pin should

be minimized.

Feedback

Senses the regulated output voltage to complete the feedback loop.

Allows the switching regulator circuit to be shutdown using logic level signals thus

dropping the total input supply current to approximately 100uA. Pulling this pin below

a threshold voltage of approximately 1.3V turns the regulator on, and pulling this pin

above 1.3V (up to a maximum of Vcc) shuts the regulator down. If this shutdown

feature is not needed, the EN pin can be wired to the ground pin.

Thermal Considerations

The TO-263-5L package needs a heat sink under most conditions. The size of the

heat sink depends on the input voltage, the output voltage, the load current and the

ambient temperature. The APE1705 junction temperature rises above ambient

temperature for a 3A load and different input and output voltages.

The data for these curves was taken with the APE1705 (TO263-5L package)

operating as a buck-switching regulator in an ambient temperature of 25℃ (still air).

These temperature increments are all approximate and are affected by many factors.

Higher ambient temperatures requires more heat sinker.
