HT1584AREZ
HTCSEMI · DC-DC Converters · ESOP-8
HT1584AREZ from HTCSEMI, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Switch node, the output of the high-side switch; a low forward drop Schottky diode to ground is required close to the SW pins to reduce switching spikes. |
| 2 | EN | input | Enable input: pulling it below the specified threshold (falling threshold 1.2V, rising threshold 1.5V) shuts the chip down, while pulling it above the threshold or leaving it floating enables the chip. |
| 3 | COMP | passive | Compensation node and output of the error amplifier where control loop frequency compensation is applied; COMP is clamped to 0.9V to 2.0V in operation and should not be pulled above 2.6V. |
| 4 | FB | input | Feedback input to the error amplifier; the output voltage is set by a resistive divider from VOUT to GND, scaled to the internal 0.8V reference. |
| 5 | GND | power_in | Ground, to be connected as close as possible to the output capacitor; the exposed pad must be connected to the GND plane for optimal thermal performance. |
| 6 | FREQ | input | Switching frequency program input: a resistor from this pin to ground sets the oscillator frequency, programmable from 100kHz to 1.5MHz. |
| 7 | VIN | power_in | Input supply for the internal control circuitry, both bootstrap regulators and the high-side switch, with a decoupling capacitor to ground placed close to this pin; operating input range is 4.5V to 28V. |
| 8 | BST | power_out | Bootstrap pin, the positive supply for the internal floating high-side MOSFET driver; a bypass capacitor is connected between this pin and SW. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
