See speciﬁ cations.

The OKL-T/1-W12 series are non-isolated Point-

of-Load (PoL) DC/DC power converters for embed-

ded applications. Featuring inspectable Land Grid

Array (iLGA) format, the OKL-T/1-W12 measures

only 0.488 x 0.488 x 0.18 inches max. (12.4 x 12.4

x 4.57 mm max.).

The wide input range is 2.9 to 14 Volts DC. The

maximum output current is 1 Amp. Based on ﬁ xed-

frequency synchronous buck converter switching

topology, the high power conversion efﬁ cient Point

of Load (PoL) module features programmable output

voltage and On/Off control. These converters also

include under voltage lock out (UVLO), output short

circuit protection, and over-current protections.

These units are designed to meet all standard

UL/EN/IEC 60950-1 safety certiﬁ cations (2nd Edition)

and RoHS-6 hazardous substance compliance.

OKL-T/1-W12 Series Programmable Output 1-Amp iLGA SMT PoLs Speciﬁcation Notes, Cont.: (7) Please observe the voltage input and output speciﬁcations in the Voltage Range Graph on page 7. (8) Output noise may be further reduced by adding an external ﬁlter. At zero output current, the output may contain low frequency components which exceed the ripple speciﬁcation. The output may be operated indeﬁnitely with no load. Due to the minimum duty cycle of the controller, operation below Vout=1.8V.

OKL-T/1-W12 Series Programmable Output 1-Amp iLGA SMT PoLs TECHNICAL NOTES Output Voltage Adustment The output voltage may be adjusted over a limited range by connecting an external trim resistor (Rtrim) between the Trim pin and Ground. The Rtrim resistor is recommended to have a ±0.5% accuracy (or better) with low temperature coefﬁcient, ±100 ppm/°C or better. Mount the resistor close to the converter with very short leads or use a surface mount trim resistor.

OKL-T/1-W12 Series Programmable Output 1-Amp iLGA SMT PoLs Input Ripple Current and Output Noise All models in this converter series are tested and speciﬁed for input reﬂected ripple current and output noise using designated external input/ output components, circuits and layout as shown in the ﬁgures below. The Cbus and Lbus components simulate a typical DC voltage bus. Please note that the values of Cin, Lbus and Cbus will vary according to the speciﬁc converter model.

OKL-T/1-W12 Series Programmable Output 1-Amp iLGA SMT PoLs Remote On/Off Control The OKL Series power modules can be speciﬁed with either a positive or negative logic polarity. See Figures 7 and 8 for On/Off circuit control. In the positive logic on/off option the unit turns on during a logic high on the On/Off pin and turns off during a logic low. In a negative logic on/off option, the unit turns off during logic high and on during logic low. The On/Off signal should always be reference to ground.
