RTQ2071BGQVT-QA-11中文资料立锜科技数据手册PDF规格书

General Description

The RTQ2071 is an integrated PMIC with three step

down converters and one high PSRR low-dropout

(LDO) regulator for automotive camera applications.

The high-voltage step down converter is operated with

input voltage range up to 18.5V for Power Over Coax

(POC) connection. Two low-voltage step down

converters provide constant output voltage. All step

down converters operate in a forced fixed-frequency

PWM mode. The LDO output voltage is easily set via

an external resistor. The RTQ2071 provides 10 power

sequences by a resistor for flexibility. The RTQ2071 is

available in a WETD-VQFN-16L 3x3 package with

dimple lead type wettable flanks.
