TPS5602
DUAL, FAST, HIGH EFFICIENCY CONTROLLER FOR DSP POWER
SLVS217 – JUNE 1999

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
APPLICATION INFORMATION
layout considerations (continued)
D When configuring the high-side driver as a floating driver, the connection from LL to the power FETs should
be as short and as wide as possible.
D When configuring the high-side driver as a floating driver, the bootstrap capacitor (connected from LH to
LL) should be placed close to the TPS5602.
D When configuring the high-side driver as a ground-referenced driver, LL should be connected to DRVGND.
D The bulk storage capacitors across VIN should be placed close to the power FETs. High-frequency bypass
capacitors should be placed in parallel with the bulk capacitors and connected close to the drain of the
high-side FET and to the source of the low-side FET.
D High-frequency bypass capacitors should be placed across the bulk storage capacitors on VO.
D LH and LL should be connected very close to the drain and source, respectively, of the high-side FET. LH
and LL should be routed very close to each other to minimize differential-mode noise coupling to these
traces. Ceramic decoupling capacitors should be placed close to where HISENSE connects to VIN, to
reduce high-frequency noise coupling on HISENSE.
D The output voltage sensing trace should be isolated from the switching node and/or inductor pulses by the
use of a ground trace or plane.
test results
The tests are conducted at TA = 25°C, the input voltage is 5 V (if not specifically noted).
