TPS62402DRCR

Texas Instruments · DC-DC Converters · VSON-10-EP(3x3)

TPS62402DRCR from Texas Instruments, in a VSON-10-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ADJ2 input Feedback/adjust input for converter 2. On fixed-output versions (TPS62401/02/03/04) this pin MUST be directly connected to VOUT2. If the EasyScale interface is used, this pin must also be connected to the output.
2 MODE/DATA bidirectional Dual-function pin. As MODE: low = Power Save (PFM at light load, auto PWM at heavy load); high = forced PWM over full load. As DATA: EasyScale one-wire serial interface with open-drain output for acknowledge; open-drain sink current must not exceed 500 uA. Interface is active when EN1 or EN2 is high.
3 VIN power_in Supply voltage input, 2.5 V to 6 V (absolute max 7 V). Connect to VBAT.
4 FB1 input Direct feedback voltage sense input of converter 1; connect directly to VOUT1. An internal feed-forward capacitor sits between this pin and the error amplifier. On fixed-output versions (or when EasyScale is used) FB1 connects to an internal resistor divider network.
5 DEF_1 input Defines the default output voltage of converter 1. On TPS62402, DEF_1 = High selects 1.8 V and DEF_1 = Low selects 1.2 V. Acts as analog input for external resistor programming when EasyScale is used.
6 SW1 output Switch node of converter 1 (400 mA). Connect to the external 2.2 uH inductor for OUT1.
7 EN1 input Enable input for converter 1, active high. VIH >= 1.2 V, VIL <= 0.4 V; input bias current <= 1 uA.
8 GND power_in Ground reference for both converters; connect to the PowerPAD.
9 EN2 input Enable input for converter 2, active high. VIH >= 1.2 V, VIL <= 0.4 V; input bias current <= 1 uA.
10 SW2 output Switch node of converter 2 (600 mA). Connect to the external 2.2 uH inductor for OUT2.
11 PowerPAD power_in Exposed thermal pad on package bottom. Must be connected to GND for proper thermal and electrical operation.
