NDP13802QB

NDP · DC-DC Converters · QFN-20-EP(5x5)

NDP13802QB from NDP, in a QFN-20-EP(5x5). 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 GND power_in Ground pin of the converter, part of the GND exposed-pad group (PAD1) that must be connected to system ground.
2 GND power_in Ground pin of the converter, part of the GND exposed-pad group (PAD1) that must be connected to system ground.
3 GND power_in Ground pin of the converter, part of the GND exposed-pad group (PAD1) that must be connected to system ground.
4 NC unconnected No internal connection; the pin table lists it as NC, while the layout note says pins 4 and 5 may be connected to VIN or GND for easier layout.
5 NC unconnected No internal connection; the pin table lists it as NC, while the layout note says pins 4 and 5 may be connected to VIN or GND for easier layout.
6 VIN power_in Power input to the regulator, specified for 7.5 V to 30 V operation with an absolute maximum VIN to GND rating of -0.3 V to 33 V.
7 VIN power_in Power input to the regulator, specified for 7.5 V to 30 V operation with an absolute maximum VIN to GND rating of -0.3 V to 33 V.
8 VIN power_in Power input to the regulator, specified for 7.5 V to 30 V operation with an absolute maximum VIN to GND rating of -0.3 V to 33 V.
9 NC unconnected No internal connection.
10 BST power_out Boot-strap pin for the high-side gate drive; connect a 0 to 20 Ω resistor (4.7 Ω typical) and 100 nF from BST to SW, with an absolute maximum BST to GND rating of -0.3 V to VIN+7 V.
11 NC unconnected No internal connection.
12 SW output Switching node connected to the inductor, with an absolute maximum SW to GND rating of -0.3 V to VIN+0.3 V.
13 SW output Switching node connected to the inductor, with an absolute maximum SW to GND rating of -0.3 V to VIN+0.3 V.
14 SW output Switching node connected to the inductor, with an absolute maximum SW to GND rating of -0.3 V to VIN+0.3 V.
15 NC unconnected No internal connection.
16 FB input Feedback input from the output divider, referenced to a 1 V internal reference (0.985 V to 1.015 V), with an absolute maximum FB to GND rating of -0.3 V to 6.5 V.
17 CSP input Positive input of the current-sense amplifier, with an absolute maximum CSP to GND rating of -0.3 V to 25 V.
18 CSN1 input Negative input 1 of the current-sense amplifier, giving a CSP-CSN1 sense voltage of 51 to 59 mV, with an absolute maximum rating of -0.3 V to 25 V to GND.
19 CSN2 input Negative input 2 of the current-sense amplifier, giving a CSP-CSN2 sense voltage of 51 to 59 mV, with an absolute maximum rating of -0.3 V to 25 V to GND.
20 FS input Frequency-setting pin: leave floating for 130 kHz or connect a resistor to GND (75 kΩ gives 300 kHz), with an absolute maximum FS to GND rating of -0.3 V to 6.5 V.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
