PIN I/O DESCRIPTION
NAME CDFP HTSSOP
GND 1 1, 2, 10, 35 — Return for control circuitry.(1)
EN 2 4 I EN pin is internally pulled up allowing for the pin to be floated to enable the device.
RT 3 5 I/O A resistor connected between RT and GND sets the switching frequency of the converter. The switching frequency range is 100 kHz to 1 MHz. When an external clock is used, RT must be selected such that the set switching frequency coincides with the frequency of the applied clock. Leaving this pin floating sets the internal switching frequency to 500 kHz and SYNC1 and SYNC2 become output clocks at 500 kHz, with SYNC1 aligned with the converter switching and SYNC2 90° out of phase.
VIN 4 6,7 I Input power for the control circuitry of the switching regulator.
SYNC1 5 8 I/O SYNC1 is an input when an external clock is provided. The frequency of the external clock should match the switching frequency that is set by the resistor between RT and GND. With an external clock applied, the converter switching action is 180° out of phase with the external clock. When RT is floating, SYNC1 serves as an output of a 500-kHz clock signal that is in phase with the converter switching action. SYNC1 can be used in combination with SYNC2 in order to connect up to four devices in parallel.
SYNC2 6 9 I/O SYNC2 is used for connecting multiple devices in parallel. For the primary device, with RT floating, SYNC2 outputs 500-kHz signal that is 90° out of phase with the SYNC1 output clock. For the secondary devices, in which RT is populated, SYNC2 is used to configure the phase of the input clock signal on SYNC1. When SYNC2 is connected to VIN, the internal clock of the secondary device is in phase with clock provided at SYNC1. When SYNC2 is connected to GND, the input clock signal at SYNC1 is internally inverted.
PVIN 7-11 11-15 I Input power for the output stage of the switching regulator.
PGND 12-17 16-22 — Return for low-side power MOSFET.
PH 18-28 23-34 O Switch phase node.
PWRGD 29 36 O Power Good fault pin. Asserts low if output voltage is low due to thermal shutdown, dropout, overvoltage, or EN shutdown, or during soft-start.
RSC 30 37 I/O A resistor to GND sets the desired slope compensation.
SS/TR 31 38 I/O Soft-start and tracking. An external capacitor connected to this pin sets the internal voltage reference rise time. The voltage on this pin overrides the internal reference. It can be used for tracking and sequencing.
VSENSE 32 39 I Inverting input of the gm error amplifier.
COMP 33 40 I/O Error amplifier output and input to the output switch current comparator. Connect frequency compensation to this pin.
REFCAP 34 41 O Required 470-nF external capacitor for internal reference.
PowerPADTM — Yes — Used for heat sinking by soldering to GND copper on printed circuit board.
THERMAL PAD 35 — — Thermal pad internally connected to GND.
PGND PAD 36 — — Return for low-side power MOSFET. Connect to PGND pins.
PH PAD 37 — O Switch phase node. Connect to PH pins.
NC — 3, 42-44 — No connect. This pin is not internally connected. It is recommended to connect these pins to GND to prevent charge buildup; however, these pins can also be left open or tied to any voltage between GND and VIN.
(1) Thermal pad and package lid are internally connected to GND for CDFP option.
