UPSRB02

Preliminary

LINEAR INTEGRATED CIRCUIT

HIGH PRECISION CC/CV

PRIMARY SIDE SWITCHING

REGULATOR



DESCRIPTION

The UTC UPSRB02 is a primary control unit for switch mode

charger and adapter applications. The controlled variable is

transferred by an auxiliary winding from the secondary to the

primary side. The device uses Pulse Frequency Modulation

(PFM) and Pulse Width Modulation (PWM) method to build

discontinuous conduction mode (DCM) flyback power supplies.

The UTC UPSRB02 operates in primary-side sensing and

regulation. Opto-coupler and TL431 could be eliminated. It also

eliminates the need of loop compensation circuitry while

maintaining stability.

SOT-26

The UTC UPSRB02 achieves high precision CV/CC regulation

and high power efficiency. It offers comprehensive protection

coverage with auto-recovery features including Cycle-by-cycle

current limiting, output over voltage protection, V_DDover voltage

protection, feedback loop open protection, short circuit protection,

leading edge blanking, OTP, V_DDunder voltage lockout, etc.


